Asking for treatments to fix dry and damaged hair is one of the most common requests stylists hear at hair salons.
The right one depends on what is actually wrong. Dry, rough hair usually needs moisture, hair that snaps needs strength (a protein or bond-building treatment), and frizz is a job for smoothing or glossing.
Chemical smoothing can be too much for fragile strands. Below are 12 salon treatments with what each one does, typical prices, and the pros and cons to weigh with your stylist.
12 Salon Treatments for Dry, Damaged Hair
These 12 options do different jobs. Some add moisture, some rebuild strength, and others remove buildup, add shine, or smooth frizz. Availability and prices vary by salon.
1. Keratin Treatment
It may seem counterintuitive to use chemicals, especially if your dryness or damage results from other chemical treatments. However, a keratin treatment can help smooth a rough cuticle, reduce frizz, and make hair feel more manageable.
It works by coating and bonding along the hair surface, which can make strands look smoother and feel less prone to snapping from day-to-day friction.
It is a smoothing service, not a repair: smoother-looking hair is not proof that chemical or heat damage has been reversed, and fragile or over-processed hair should be assessed before booking.
The process also relaxes the hair pattern a bit, so if you have curly hair and want to keep those curls intact, this might not be the best option for you.
Note: Some keratin treatments can permanently loosen your natural curl pattern. If you want to preserve your curls, discuss the exact formula and process with your stylist; a “curl-safe” label is not a guarantee.
Chemical Smoothing Safety
Many smoothing services release formaldehyde gas (or use formaldehyde-releasing ingredients) when heat is applied. A “formaldehyde-free” label alone does not make a treatment suitable for you: ask for the exact product name, its ingredient list, and its safety information, and avoid glyoxylic-acid straightening products, which French health authorities linked to cases of acute kidney injury in 2024. If you are pregnant, discuss any chemical smoothing service with your prenatal clinician before booking, and make sure the salon uses good ventilation.
Those with straight and wavy hair, or those who don’t mind relaxing their curls a bit, will love having less frizz and fewer flyaways after a proper keratin treatment.
These treatments typically range from $250 to $500.
Pros
- Reduces frizz and improves manageability
- Makes hair look smoother and shinier
- Treatment can last up to 6 months
Cons
- Needs specific aftercare products to help results last
- May change the natural curl pattern
- Frequent treatments can stress already fragile hair
2. Detoxing Treatment
Hair detoxing means getting rid of excess oils, dirt, and product buildup stuck in your hair. Usually, this requires a specialized detoxifying shampoo and conditioner, but there are plenty of treatments you can make at home.
A hair detox gives you a deeper, more intense clean that can remove stubborn product buildup as well as scalp residues. It can work for many hair types and can leave you with healthier-looking, shinier hair. It’s like a factory reset for weighed-down strands.
Note: These treatments are clarifying and can strip artificial hair color or toner. Consult your stylist if you have recently colored your hair.
Given that it’s a more intense treatment, it’s essential to follow it up with a conditioner or mask that will soften and help protect the hair from feeling stripped.
Pros
- Removes excess oils, dirt, and product buildup
- Improves scalp feel and freshness
- Works for many hair types
Cons
- Can strip hair of natural oils if overdone
- May need regular sessions for sustained results
3. Kérastase Fusio-Dose
Kérastase Fusio-Dose is another salon treatment that works great for all hair types. Like many in-salon systems, it can help improve softness, shine, and frizz.
A hairstylist may use this treatment instead of a standard conditioner on your hair. But the process isn’t as simple as squirting some liquid on your hands and rubbing it in.
With Kérastase Fusio-Dose, a hairstylist may take up-close photos of your strands to get the best look at what to support, be it dryness, color stress, heat stress, or more. It costs around $30.
Pros
- Customized according to specific hair needs
- Effective for improving dry and damaged hair
- Five-minute in-salon service
Cons
- Requires frequent salon visits for upkeep
- A few customers reported greasy scalps after treatment
4. Brazilian Blowout
A Brazilian Blowout is a go-to for blasting away frizz and making your hair smooth and sleek. It is a form of smoothing treatment that uses chemicals, so it can be risky for those with sensitive skin or scalp conditions.
The treatment smooths the hair by coating it with a protein layer. This layer can help protect the hair from humidity, heat styling, and future styling stress.
Chemical Smoothing Safety
Many smoothing services release formaldehyde gas (or use formaldehyde-releasing ingredients) when heat is applied. A “formaldehyde-free” label alone does not make a treatment suitable for you: ask for the exact product name, its ingredient list, and its safety information, and avoid glyoxylic-acid straightening products, which French health authorities linked to cases of acute kidney injury in 2024. If you are pregnant, discuss any chemical smoothing service with your prenatal clinician before booking, and make sure the salon uses good ventilation.
A Brazilian Blowout can last approximately 12 weeks and costs around $350.
Pros
- Significantly reduces frizz and smooths hair texture
- Leaves hair looking glossier
- Doesn’t permanently change the hair’s structure in the way some relaxers do
Cons
- May involve formaldehyde or formaldehyde-releasing ingredients
- Lasts only about 10-12 weeks
- Not ideal for extremely fragile, over-processed hair
5. Bond Building Treatments (Olaplex & K18)
Bond builders are the biggest modern upgrade in salon repair, especially if your hair is damaged from bleach, highlights, or frequent heat. Unlike many conditioners that mainly coat and soften, bond builders are designed to support the internal bonds that get stressed during chemical services.
Olaplex is the most well-known. In salons, it’s often added to lightening or coloring services, or used as a standalone treatment to improve strength and reduce breakage. K18 is another popular option that focuses on molecular-level repair and can be used in-salon after chemical services.
Pricing varies by salon and whether it’s an add-on or a full service, but it’s commonly offered anywhere you color or lighten your hair.
Pros
- Best option for bleach or chemical damage
- Helps reduce breakage and improves hair strength
- Works well alongside moisture masks and trims
Cons
- Results depend on the level of damage and consistent aftercare
- Can feel less “slippery” than heavy conditioners, especially right after treatment
6. Multi-Step Repair Systems (e.g., Japanese Treatments)
Multi-step repair systems are salon services that layer hydration and conditioning in steps, often focusing on softness, smoothness, and shine. Brands like Milbon (Inphenom) offer intensive multi-step treatments.
This five-step hair treatment is an excellent option if your hair requires significant hydration. These treatments can help improve softness and smoothness by supporting the cortex and closing the cuticle and locking in moisture, which can help reduce future damage.
The results include hair that feels strong and soft, which can last for several weeks after the treatment. The average price is around $75, and many believe it is well worth it.
Pros
- Makes stiff, dry, or damaged hair feel silky soft and look shinier
- Locks moisture in the hair to help prevent further damage
Cons
- Not available in all professional salons
- May not offer enough repair for heavily bleached hair
7. Hair Glossing Treatment
It’s no secret that excessive hair dyeing can damage and dry out your locks. A hair gloss is a gentle, demi-permanent form of coloring that offers a lower-maintenance alternative to permanent dye.
Many hair glosses include conditioning agents like amodimethicone and behentrimonium chloride, which are helpful for smoothing dull hair and boosting shine.
You can choose between clear gloss, which will give your hair shine, or colored gloss, which will add shine as well as color.
The whole process can last up to 40 minutes, and a good 20 minutes of that is leave-in time.
You can get this treatment at a salon or do it at home. Results usually last around 4 weeks.
Pros
- Adds a luminous shine to the hair, making it look healthier
- Enhances and revives the color of dyed hair
- Helps smooth the hair cuticle, reducing frizz
Cons
- The effects are relatively short-lived, requiring regular treatments
- May lead to product buildup on the scalp if overused
8. Professional Deep Conditioning Masks
Professional deep conditioning masks are one of the best salon treatments for dry and damaged hair that needs serious hydration after heat, stress, and over-processing.
Some masks contain a blend of jojoba oil and vitamins, which can help condition your strands and nourish your scalp. Together, they support softness, add shine, and improve manageability.
Buying a mask yourself can cost around $8, but a salon may charge about $20 – $30 for a deep repair treatment like this.
Pros
- Provides deep conditioning for dry, damaged hair
- Helps improve softness and manageability
- Leaves hair feeling smoother
Cons
- Requires time to sit in the hair for effective results
- Might be too heavy for those with fine or oily hair types
9. Protein Treatments
Protein treatments are excellent for damaged hair because they help reinforce the hair, reduce brittleness, and improve strength.
Note: A single damp strand’s stretch cannot diagnose exactly what your hair needs, so treat the old elasticity test as a rough clue at best. If your hair feels gummy, unusually brittle, or keeps breaking, pause chemical services and have a stylist assess its condition before adding protein or anything else.
In salons, you’ll often see options like Redken CAT (a quick protein boost). For very damaged hair, some people use stronger at-home options like Aphogee Two-Step, but it’s best to get guidance from a stylist if your hair is fragile.
Most protein treatments give a temporary strengthening effect; how long it lasts and how often it can be repeated depends on the product, so follow its directions.
If your hair starts to feel stiff, rough, or snappy, that can be a sign of too much protein and too little moisture, so ask your stylist to reassess before the next one.
Pros
- Helps reinforce hair structure, reducing breakage
- Particularly beneficial for hair weakened by coloring or heat styling
- Improves elasticity when used correctly
Cons
- Excessive use can make hair hard and brittle
- Focused more on strength, less on hydration
10. Hot Oil Treatment
While protein treatments target weakened strands, hot oil treatments at the salon specifically target dry hair.
A stylist will massage warmed oil into the scalp and hair. This can help soften the hair and improve slip, which makes detangling easier.
This treatment is excellent for dry scalps, as the oil can help moisturize the skin. Prices typically range from $10 to $30 as an add-on service, while standalone treatments will cost more.
Pros
- Great for deep moisture on scalp and hair
- Warm oil can feel relaxing and soothing
- Can use a variety of oils based on hair type and need
Cons
- Application and cleanup can be messy and take time
- Those with scalp issues might find hot oil treatments uncomfortable
11. Deep Conditioning Treatment
Deep Conditioning offers the best of both worlds for dry, damaged hair: intense moisture and better manageability. This salon treatment is great for people with frizzy, flyaway hair.
It overlaps with the masks in entry 8, and the difference is mostly format. A mask is usually one product left on for a set time; a deep conditioning treatment is a service where the stylist chooses the formula for your hair and may add heat or steam to help it absorb.
Deep conditioning infuses the hair with moisture and softening ingredients, which helps reduce frizz and improve shine. You may require it more often if you use heat or color on your hair regularly.
The average price of a deep conditioning treatment is $30.
Pros
- Delivers deep hydration to dry, damaged hair
- Makes hair softer and reduces frizz
- Can be customized with various ingredients based on hair needs
Cons
- Effects are temporary, so you may need regular treatments
- Can be too heavy for those with very fine hair
12. Scalp Treatment
Salon scalp treatments usually mean a scalp scrub or clarifying cleanse to lift product residue and surface oil, followed by a massage with a nourishing oil or serum.
They are cosmetic services for scalp comfort and cleanliness. They do not repair damage along the hair lengths, and hair-growth devices or clinical hair-loss procedures are a different subject and outside this guide.
A dry, flaky scalp often feels better after a gentle cleanse and massage, but ask your stylist to pick products suited to your scalp and to skip vigorous scrubbing if it is sensitive.
Note: If you have psoriasis, eczema, or any open sores, skip salon scalp treatments until you have consulted a board-certified dermatologist.
Pros
- Can help reduce visible flaking and leave the scalp feeling cleaner and calmer
- A scalp massage can feel relaxing
- Can support dry, damaged hair with nourishing products
Cons
- Not suitable for certain scalp conditions (psoriasis, eczema)
- Does not repair breakage along the hair lengths
What Salon Treatments Can and Can’t Do
Salon treatments can add moisture back into dry strands. A moisturizing treatment is especially useful in winter, when drier air strips hair of its natural moisture.
They can also improve the look and feel of hair that has been stressed by chemicals, coloring, heat, environmental factors, or over-styling: smoother, shinier, less frizzy, with more bounce and better resistance to breakage and split ends.
What they cannot do is change how your hair grows. No treatment of the hair shaft makes hair grow faster or thicker; what less breakage does is help you keep the length you grow.
The advantage of a salon over an at-home treatment is that the stylist can look at the actual damage (dryness, breakage, previous color or chemical work) and tailor the service to it.
How Often Should You Go?
For conditioning treatments (masks, deep conditioning, hot oil), every four to six weeks is a common rhythm. If your hair is very dry or damaged, you might need to go more often at first and then taper off to every six weeks as it improves.
Smoothing services such as keratin and Brazilian Blowout last months and are not repeated on that schedule. Protein and bond-building treatments follow their own product directions, so ask your stylist to set the timing by the exact product and your hair’s condition.
Hair that is already breaking needs a gentler plan, not a stronger one. Pause further chemical services until a stylist has assessed the damage, and expect a trim of the worst ends to be part of the fix.
Change the habits that caused the damage, or no treatment will hold.
So, if you have dry, damaged hair, consider trying one of the above most popular salon treatments. The right option can help soften strands, boost shine, and reduce breakage, especially when paired with good at-home care.
