Natural Oils that Add Volume to Fine Hair

There are many natural oils that can be used to add volume to thin or fine locks if applied correctly! If you are wanting to make a natural hair styling product it’s best to use lightweight oils that won’t coat the strands and weigh them down. Light oils include sweet almond oil, Argan oil, and grapeseed oil. If you have low porosity hair it’s a good idea to always use lighter oils.

Heavier oils such as olive oil, castor oil, coconut oil, are great choices for hair masks since they help to condition the hair and add volume. They also help to nourish the hair follicles, promoting growth and thicker hair. Rosemary essential oil and pumpkin seed oil are also useful for adding volume to fine hair.

Olive Oil

You can use olive oil on its own as a hair treatment to promote thicker hair. In fact my DIY olive oil hair mask is one of my go-to treatments when my hair needs an extra boost.

Olive oil is full of healthy nutrients including vitamin E and omega 3 fatty acids which protect the hair from damage, moisturise it, and encourage fuller locks. Olive oil also helps to seal moisture into the strands, helping your hair to retain its shine and reducing frizz.

When I use olive oil as a natural hair thickening treatment, I combine with 1 teaspoon of lemon juice to give the hair extra shine. Massage the oil into the scalp and and hair and leave it for at least an hour before washing off with a clarifying shampoo.

Other Natural Ingredients to Thicken Fine Hair


Eggs are a well known for improving hair health. They are rich in biotin, folate and vitamins A and E which all help to keep the hair healthy and thick. The yolk of the egg is rich in fats which moisturise the hair and scalp, and the ​egg white contains proteins which help to strengthen the hair shaft and reduce breakage

Eggs are a great natural thickener for the hair, and can work especially well at making fine, limp hair appear thicker. If you use eggs in your hair treatments then I would recommend that you apply the mixture to wet hair that has been shampooed beforehand. Then just cover with a shower cap before rinsing out after 20 minutes.

Aloe Vera Gel

Aloe vera has been used for centuries in health and beauty treatments, and as a natural hair thickener for fine hair. The plant is a well known natural remedy that can help to stimulate hair growth, strengthen the hair shaft and reduce breakage.

Aloe vera gel contains vitamins A, C and E, vitamin B12, folic acid, choline and multiple enzymes, minerals and fatty acids which nourish the hair follicle and promote thick hair. (source)

Aloe vera gel can be used as a natural thickener for fine hair by applying the aloe vera gel onto scalp after shampooing. Let it sit for 3-5 minutes before rinsing off.

Avocado is a nutrient-dense fruit that contains monounsaturated fat which has been linked with healthier and shinier hair. Avocados are also full of beneficial nutrients such as potassium, iron, zinc and vitamins A, B6 and E which all contribute to growing thicker hair.

You can use pureed avocado in your hair treatments, or avocado oil. The oil may help to moisturise the hair and make it shinier, but I prefer to use mashed avocado. This is because I’ve found it leaves less residue on the strands and is easier to wash out.

Be sure to use an organic avocado that has creamy flesh. I normally use mashed avocado with olive oil and massage it into my scalp and hair before leaving it for an hour.

Onion Juice

Onion juice is another natural remedy that can stimulate hair growth and thicken the hair. Onions contain sulfur which helps to improve blood flow in the scalp and stimulate hair growth. It is also thought to prevent premature greying and dandruff.

Sulfur is found in amino acids such as keratin. Keratin is protein that is required for growing strong hair. When onion juice is applied to the hair and scalp it can provide extra sulfur which can help with the growth of longer, thicker hair.

Onion juice is also believed to promote blood circulation in the scalp and increase collagen production. Some studies have shown that it may even be beneficial in preventing hair loss, and a natural treatment for alopecia.

Apple Cider Vinegar

Apple cider vinegar is a popular remedy that can be used to reduce hair loss and increase hair growth. It contains rich amounts of vitamins, minerals and other nutrients which nourish the hair follicles, improve blood circulation in the scalp and fight the bacteria which can cause dandruff.

A simple remedy for thinning hair is to mix apple cider vinegar with water into a 50/50 mix. Rinse the mixture through your hair after shampooing or wetting, before rinsing it off thoroughly.

Indian Gooseberry (Amla)

Indian Gooseberry (also known as Alma) has been used since ancient times in Indian Ayurvedic medicine to promote healthier hair. The plant is rich in vitamin C which can help to reduce hair fall and encourage new hair growth.

Indian gooseberry juice mixed with lemon juice makes a great natural thickener for thinning hair. Apply the mixture to wet hair, leave it in overnight if possible then rinse out thoroughly in the morning.

Coconut Oil and Onion Juice

To make this treatment, you will need: 2 tablespoons of coconut oil mixed with 4 teaspoons of onion juice (this can be made by finely mincing one medium onion, then straining the juice using a cheesecloth.

Since onion juice contains high amounts of sulfur, which helps to increase circulation in the scalp, I use this recipe as as scalp treatment.

Coconut Oil and Rosemary Oil

This treatment includes 2 tablespoons of coconut oil mixed with 2 tablespoons of rosemary oil. Rosemary is one of my favourite essential oils for hair growth. It has been used as a traditional remedy for stimulating the scalp for centuries, and I find it works well combined with coconut oil!

Coconut Oil and Apple Cider Vinegar

This treatment includes 1 tablespoon of coconut oil mixed with 3 tablespoons of apple cider vinegar. ACV helps to restore the scalp’s pH balance, which is especially beneficial for those with itchy, flaky or oily scalps.

The combination of coconut oil and apple cider vinegar helps to improve hair texture as well as give life to flat or limp hair.

Coconut Oil with Avocado

To make this treatment, you will need: 1 tablespoon of coconut oil mixed with one mashed avocado . Avocado is one of my favourite fruits to use in my home remedies! The healthy fats in avocado are not only great for moisturising the scalp, but they also work as a natural hair thickener!

I found that avocado combined with coconut oil creates a healthy scalp and promotes the right environment for hair growth. This mixture also leaves the hair beautifully shiny and strong.

Coconut Oil and Jojoba Oil

This treatment includes 1 tablespoon of coconut oil mixed with 2 tablespoons of jojoba oil . Jojoba is very similar to the natural oils naturally produced by your scalp, so it’s great for moisturizing strands and encouraging hair growth.

I massage this treatment into my scalp before shampooing to help protect the hair and make it appear fuller and thicker.

Olive Oil, Eggs and Aloe Vera Gel

This treatment includes 1 tablespoon of olive oil mixed with 1 tablespoon of aloe vera gel and 2 eggs. Whip the two eggs before combining them with the olive oil and aloe vera gel.

Apply the mixture to the hair and scalp for at least an hour before gently rinsing out. The protein in the eggs along with the vitamin B in the aloe vera, will deeply condition your hair and promote growth.

Avocado and Indian Gooseberry (Amla)

To make this treatment, you will need: 1 tablespoon of avocado combined with 1 tablespoon of indian gooseberry powder . Leave this mixture on your scalp for at least an hour before shampooing with a clarifying shampoo.

This mixture is especially beneficial for hair loss and hair thinning, as avocado and amla both work to promote overall scalp health, restore pH levels and encourage circulation in the scalp.

Jojoba Oil, Pumpkin Seed Oil and Rosemary Oil

To make this treatment, you will need: add 2 tablespoons of jojoba oil with 2 teaspoon of pumpkin seed oil and 1 teaspoon of rosemary oil . Apply this mixture to the scalp for at least an hour before rinsing out.

The combination of jojoba, pumpkin seed and rosemary oils help to stimulate hair growth by promoting blood circulation in the scalp. They also increase cell turnover rate, which helps to remove dead skin cells and allows your natural hair oils to penetrate deeply into the scalp.
