How Do I Warm Up My Ashy Hair at Home?

Have you recently dyed your hair ash blonde, ash brown, or any other ashy tone and found that the color looks too cool? Don’t worry; you can warm up your ashy hair at home!

While visiting a salon is always an option, you can also try a few things at home to add warmth to your hair. In this article, we’ll discuss some tips and tricks for DIY ashy hair warm-up.

While a cool, silvery tone is often the desired result of blonde color treatments, sometimes it’s just not for you. You may wonder, how do I warm up my ashy hair at home?

Adding warmth to your ashy hair can be as simple as using a color-depositing shampoo or conditioner during your final showering step. If you plan to use a clarifying or anti-dandruff shampoo to fade a too-ashy result, wait at least 72 hours after coloring.

This simple fix can give you the champagne hue, honey blonde, or another warm tone you sought.

What Causes Hair To Be Ashy?

Ash blonde refers to the cool tone of the hair, regardless of how light or dark it is. It is characterized by blue, violet, or green undertones that cancel out warmth, and it can range from a darker, cool medium ash blonde to a pale silvery platinum. Any ashy color is caused by the blue, violet, or green-based undertones in toning products or hair dyes.

Ash brown is a cool brunette shade with blue, green, or violet undertones. Applying brown color over blonde can result in an ashy brown with a grey-green undertone.

Always consider your natural hair color when selecting a hair color product. The picture on the box only represents what your hair might look like following the application.

Using a color wheel to understand the base colors when choosing a new color may prevent any unwanted ashy mishaps.

Ashy Hair From Toning

After bleaching treatments, toners are used to correct blonde shades or neutralize the remaining orange, red, or yellow pigment. Leaving toner on too long or using a shade that has the wrong base colors can leave hair a cool ashy color.

As with using a brown permanent hair color on blonde hair, using a brown toner with a blue or purple base on blonde hair can result in an undesired ashy brown color.

How To Warm Up Ashy Hair at Home

You look in the mirror and see a color that is too ashy or silver. Maybe the color has too much of a cool tone for your dress and skin tone. Whatever the reason, you want to change up those ashy locks to something warmer.

#1: Washing Out The Ashy Tone

The simple act of washing your hair will reduce ashy hair color over time.

Bleached hair naturally has a warm yellow undertone. Washing away the cool ash toner allows natural warmth to shine through again.

Both ash blonde and ash brown colors will fade to a lighter, often brassy color after several weeks, depending on how often you shampoo your hair and what type of shampoo you use.

Clarifying shampoos often have a higher pH (often 8.0+) compared to standard shampoos (around 5.5). This higher alkalinity can swell the hair cuticle and speed up fading, which may help reduce an overly cool, ashy tone over time.

Safety Warning: Wait at least 72 hours (3 days) after bleaching or dyeing before using clarifying or anti-dandruff shampoos. This window allows your scalp’s acid mantle to regenerate and restore its natural pH balance, preventing chemical burns and irritation. If your color is too ashy immediately after a salon visit, contact your stylist for a professional correction rather than attempting it at home.

You can also use anti-dandruff shampoos on color-treated hair to fade the color over time.

Note: Anti-dandruff shampoo can be very drying, so always follow up with a deep moisturizing conditioner to keep your strands healthy.

#2: Adding Warmth With New Hair Color or Toner

Adding a hair color with a semi-permanent or demi-permanent dye can be done with lowlights, layers of red or caramel, or even an all-over deposit-only application.

Strict Rule: Never use permanent hair color (box dye) to correct tone on bleached or highlighted hair. Permanent dye contains ammonia and higher-volume developers meant to lift virgin hair. Instead, use a demi-permanent gloss or semi-permanent glaze with a deposit-only developer (usually 6-volume / 1.9% or lower) or an acidic activator. Do not use 20-volume developer, as it can lift your natural root color and cause unnecessary damage to previously bleached strands.

Another way to add warmth to overly ashy hair is with toner. Toners are used to remove brassiness or yellow after bleaching, but they can also be used to add warmth to ashy hair.

Select a toner based on the specific type of ash you are seeing:

1. Greenish Tone: Use a rose gold or warm beige toner.

Green is neutralized by red. However, a pure red toner is too dark for blonde hair. Rose Gold contains soft red pigments that correct the green without turning your hair pink or muddy brown.

2. Blue or Silver Tone: Use a peach, apricot, or soft copper toner.

Blue is neutralized by orange. Soft orange shades like peach or apricot will warm up the icy blue tones instantly without making your hair look like a safety cone.

3. Violet or Grey Tone: Use a golden-beige toner.

Violet is neutralized by yellow. A golden-beige toner adds a natural, sun-kissed warmth that cancels out the dull grey look.

Once you have the correct color or toner, apply the mixture using a bowl and brush application method. If you are applying in the shower, gently distribute with a wide-tooth comb or your fingers using a ‘gliding’ motion.

Do not rub or scrub the hair strands together, as wet, chemically treated hair is prone to snapping.

Stylist’s Tip: If your hair feels ‘heavy’ or looks too dark because of excess toner (over-toning), focus on Method #1 (Washing) first. Adding a warm gloss to hair that is already saturated with pigment can make the color look muddy or darker than intended.

#3: Adding Warmth With Color Depositing Products

For hair that is too ashy, where using a permanent dye or high-volume developer could cause additional damage to your hair, using a color-depositing hair product might be the best solution.

Color-depositing shampoos and conditioners work to coat the hair with pigment. The longer these products are left on the hair, the more intense the color will be.

You can also use color-depositing masks, glosses, and sprays to add depth and warmth to ashy hair. These products add color lasting five to fifteen washes, and changing the frequency of use can change the tone of your hair from week to week.

So, How Can You Warm Up Your Ashy Hair at Home?

There are many ways to warm up ashy hair right at home. Try applying a demi-permanent gloss or semi-permanent warm toner all over, or even adding a caramel tone to blend warm colors throughout.

Or, use color masks and color-depositing hair products to add different color facets and warmth to ashy hair. If you opt for the clarifying shampoo method, just remember to follow the 3-day safety waiting period mentioned earlier to keep your scalp healthy.
