Here are some of the best oils for hair growth and thickness:

1. Coconut oil

Coconut oil is a favorite for many when it comes to hair care. It penetrates the hair shaft deeply, reducing protein loss and adding essential moisture. This results in stronger, healthier hair that can grow longer without breaking.

One standout feature of coconut oil is its lauric acid content, which has antifungal properties. This helps combat dandruff and maintain a healthy scalp. 

To use, warm a small amount of coconut oil and massage it into your scalp and hair, leaving it on for at least 30 minutes before washing it out.

2. Argan oil

Argan oil, often referred to as "liquid gold," is packed with Vitamin E and fatty acids. These nutrients protect your hair from damage and improve its elasticity, preventing breakage and split ends, which is crucial for growing longer hair.

To use argan oil, apply a few drops to your palms, rub them together, and then work the oil through your hair, focusing on the ends. 

You can use it on damp hair before styling or as a finishing touch on dry hair to add shine and smoothness.

3. Jojoba oil

Jojoba oil is unique because it closely mimics the natural oils produced by our scalp. This makes it an excellent moisturizer that doesn't leave your hair feeling greasy. It's perfect for preventing breakage and split ends, which is essential for hair growth.

To use, apply a few drops of jojoba oil to your scalp and hair, then massage it in. You can leave it on for 20 minutes before shampooing or use it as a leave-in conditioner.

4. Rosemary oil

Rosemary oil has gained popularity for its ability to stimulate hair growth from the root. It also helps tackle dandruff and promotes a healthier scalp, both essential for optimal hair growth. 

Interestingly, rosemary oil can inhibit the production of DHT, a hormone linked to hair thinning and premature graying.

To use rosemary oil, mix a few drops with a carrier oil like coconut or jojoba oil and massage it into your scalp. Leave it on for at least 30 minutes before washing it out.

5. Olive oil

Olive oil is rich in Omega-3 fatty acids and antioxidants, making it a fantastic choice for strengthening hair and protecting it from damage. It adds instant shine and moisture, which helps prevent breakage and dullness.

To use olive oil, warm a small amount and massage it into your scalp and hair. Leave it on for about 30 minutes, then rinse it out with shampoo.

6. Castor oil

Castor oil is known for its ricinoleic acid content, which improves blood circulation to the scalp, stimulating hair growth. It also has antifungal properties that help keep the scalp healthy and dandruff-free.

To use, massage castor oil into your scalp and leave it on for a few hours or overnight before washing it out. Because it’s quite thick, you might want to mix it with a lighter oil like coconut or jojoba.

7. Avocado oil

Avocado oil is rich in monounsaturated fats, which are perfect for nourishing and softening hair. It’s especially beneficial for those with coarse or dry hair, helping to reduce tangles and knots.

To use, apply avocado oil to your hair and scalp, leave it on for at least 30 minutes, and then wash it out with shampoo. It can also be used as a leave-in conditioner for added moisture.

8. Almond oil

Almond oil, with its high Vitamin E content, nourishes and strengthens hair, reducing hair fall and promoting thicker hair. It also leaves a pleasant, sweet scent.

To use, apply almond oil directly to your scalp and hair, massaging it in gently. Leave it on for a few hours or overnight before rinsing it out.

9. Grapeseed oil

Grapeseed oil is a lightweight option that works well for all hair types. It’s rich in antioxidants and helps reduce frizz, making it perfect for use in humid climates.

To use, apply a small amount of grapeseed oil to your hair, focusing on the ends. It can be used on wet or dry hair to add shine and control frizz.

10. Tea tree oil

Tea tree oil is famous for its calming and soothing effects, making it great for the scalp. It helps unclog hair follicles and promote growth, leaving you with a healthy, dandruff-free scalp.

Mix a few drops of tea tree oil with a carrier oil and massage it into your scalp. Leave it on for 15-30 minutes before washing it out.

11. Lavender oil

Lavender oil not only smells amazing but also has properties that promote hair growth and reduce stress, which can contribute to hair loss. It improves blood circulation in the scalp, encouraging healthy hair growth.

To use, mix a few drops of lavender oil with a carrier oil and massage it into your scalp. Leave it on for at least 30 minutes before rinsing it out.

Effective ways to use hair oil for growth and thickness

There are several effective ways to use hair oil to promote growth and thickness. Here are some methods to try:

Use as a scalp treatment

A quality scalp treatment can help restore your hair starting at the root. Packed with beneficial oils like rosemary oil, it boosts hydration, circulation, and hair growth.

Apply and leave it on for 5-7 minutes for immediate benefits. Use it twice a week for dry and irritated scalps, or twice a month for preventative care.

Add to your deep-conditioning hair mask

Combining a good hair mask with a few drops of hair oil can restore life to dry locks. This mix hydrates your hair and leaves it feeling soft and manageable.

Use a hair mask once or twice a week, adjusting based on your hair’s needs at that moment.

Apply as a stand-alone oil treatment

Using hair oil as a stand-alone treatment is an excellent way to promote hair health. You can use it overnight or as a pre-shower fix. The longer your hair absorbs the nutrients, the more benefits you'll see.

Ingredients like honey, coconut oil, and sweet almond oil provide antioxidant repair, nourishment, and a boost of Vitamin E to prevent breakage.

Use a hair repair serum

For hair that's had a rough time, a hair repair serum can be an excellent solution. Combining oils with keratin strengthens the hair, covering breakage from every angle.

Keratin, the natural protein that makes up our hair, boosts lower levels to strengthen dull and weakened hair, simultaneously protecting it from environmental damage or heat.

Finish with oil in your styling routine

Applying hair oil as the final step in your styling routine can combat frizz and add an immediate shine for a polished and healthy look.

Simply apply a drop or two into your hand and run it through the mid-lengths to the end of your hair.

Do hair-growth oils really promote hair growth?

Yes, several scientific studies suggest that certain oils do boost hair growth.

These oils condition the hair and scalp, stimulate collagen production through massaging, and result in stronger follicles and reduced hair fall. They penetrate and promote hair growth in their respective ways, conditioning the hair shafts to reduce friction and breakage.

Are there any side effects of using oils for hair growth?

While hair oils can be beneficial, some essential oils are quite strong and may cause allergic reactions if used in large amounts.

  • Conduct a patch test: If you have sensitive skin, always perform a patch test on your wrist or inside your elbow using only diluted essential oils.
  • Watch for symptoms: Symptoms of allergic reactions include irritated or red skin, difficulty in breathing, itchy skin, severe dermatitis, itchy and painful rashes, and swelling of the tongue.

Always dilute essential oils before use and consult with a healthcare provider if you have concerns.
