The 10 Best Oil for Hair Growth and Thickness

Learn about the best hair oils for hair growth and thickness and the mistakes that are preventing your hair from thriving.

Many people experience thinning, shedding, or hair loss throughout their lives. This could be caused by stress, but it’s also often caused by a lack of care for your hair. Your hair may seem like it always knows what to do.

However, without proper care, your hair strands can weaken. This may result in damage and breakage. Also, your scalp may become clogged with build-up, preventing proper hair growth.

In order for your hair to grow, the hair follicles must be stimulated, and the strands must remain strong. An effective way to strengthen your hair is by using hair oils. Hair oils protect, nourish and strengthen your hair, while also soothing your scalp and giving it the nutrients it needs to thrive.

This article will explain what prevents hair growth and thickness and offer tips on how to promote hair growth and thickening. We will also give our picks of the best oil for hair growth and thickness.


What Prevents Hair Growth and Thickness

What Prevents Hair Growth and Thickness

You may think that natural hair growth only has to do with having a healthy scalp, but this is not true. Hair growth and thickness go hand-in-hand, and the health of your hair is equally as important as the health of your scalp.

Hair growth requires length retention as much as scalp stimulation. If your hair is dry and brittle, it will begin to break off, and if it breaks off at a rate that is quicker than it’s growing, you’ll notice that you’re losing length.

Likewise, your scalp must remain healthy and clean to allow your hair follicles to grow. By ensuring that your scalp is nourished and moisturized — especially if you regularly have dry scalp and dandruff – you can help with the overall growth of your hair. You can protect against having an itchy scalp and strengthen against hair breakage.

However, avoid adding too much product to your scalp, which may cause build-up and oily hair and prevent your hair follicles from thriving.

For this reason, it’s important to always keep your hair moisturized and nourished, especially the ends of your hair, which may be too far for the natural oils of your scalp to actually reach.

Hair oils, including essential oil, can greatly help with hair retention, as well as aid in soothing your scalp and preventing irritation or inflammation. The best oil for hair growth will benefit both your strands and your scalp to promote the growth of thick, healthy hair.


Why Use Oil for Hair Growth and Thickness?

Hair essential oil can be great for your hair in a number of ways. Depending on the type of oil, hair oil can be used to soften and add shine to your strands. It can also be applied to your scalp to soothe it or to stimulate hair growth.

With regular use, hair oil (or beard oil for the men) will make your hair stronger and serve to protect it against damage, making it easier to retain length and promote visible hair growth.

If you do choose to use hair oil for hair growth and thickness, know that less is more. Be sure not to overdo it and to keep up with washing your hair.

You always want to keep your hair clean and prevent build-up, so it’s best not to keep oil in your hair or scalp for more than one day before washing it out.

Some hair oils that are great for hair growth include:

  • Coconut Oil: Coconut oil is a very popular oil to use in hair. It’s beneficial to the hair follicles, helping to stimulate them to promote hair growth, and it can help reintroduce natural moisture to your hair.
    It’s an easy oil to combine with other oils in order to maximize benefit. Coconut oil works especially well on natural afro-textured hair.
  • Jojoba Oil: Jojoba oil is not only ideal for your hair, but it works great on your face as well. It is rich in vitamins and minerals that have been proven to nourish and strengthen hair, and it is a great oil to help moisturize the scalp.
  • Castor Oil: Castor oil has gained popularity when it comes to hair growth and restoration of hair health. It is known to reduce hair thinning and restore circulation at the scalp. You can combine it with other oils or use it as an oil treatment before you wash your hair.
    If you want the best quality castor oil, look for Jamaican Black Castor Oil. It’s usually darker and thicker in consistency, but it is more nutrient-dense than regular castor oil.

Additional Tips for Hair Growth and Thickness

Applying hair oil does not guarantee that your hair will grow and thicken, but used in conjunction with other methods, it gives your hair the best chance to thrive.

Other tips for hair growth and thickness include:

  • Massage: When applying oil to your hair, massage the oil into your scalp. Not only will a scalp massage help the oil better penetrate into your follicles, but the massage itself can stimulate the scalp to promote hair growth and improve hair thickness.
    Try to take a couple of minutes a day to give yourself a light massage. If you intend to use oil to massage your scalp, you may want to opt for a lighter oil, such as coconut or jojoba oil.
  • Treatments: Do either a deep conditioning treatment or hot oil treatment regularly (at least once a week).
    If you want to use oil for hair treatments, choose oils that are good at penetrating the hair shaft to help ensure that your hair is absorbing as many nutrients as possible.
  • Extra Care for Natural Hair: The importance of adding moisture is especially true for curly or afro-textured hair.
    The pattern of these curly hair types makes it even more difficult for the natural oils of the scalp to travel to the ends of the hair. If you have a more kinky, coiled or curly hair pattern, you may benefit from using a thick oil such as castor oil.


Using oil in your hair is a great way to help improve your hair growth and thickness. There are a variety of oils to choose from that will benefit your hair and help with healthy hair growth, so be sure to take your time when choosing one that works for you.

Start by trying small quantities of different pure oils to get an idea of the type that might work for your hair. Although it may take time to see results, the best oil for hair growth and thickness is out there for you. All you need is patience!
