How to Thicken Hair Naturally - 5 Ways

Looking for a simple solution to thicken hair naturally? I’m always trying to find new ways to make my long and thin hair look thicker. But, many products you find in the store for volumizing hair contain harsh chemicals and can often cause more harm to your delicate hair. If you’re like me, you want to have full thicker hair that is both shiny and healthy looking and the best way to get this is by using only natural ingredients.

Not only are the harsh chemicals bad because they can be absorbed through your skin, but they can also cause your hair to break more easily or cause hair loss as well. When I was in college quite a few years ago, I used to tease my hair and spray it with toxic hairspray to make it appear thicker. Even though it worked for some time, it just caused more damage to my hair and the toxic chemicals in the hair spray were frightening. But, there’s no need to use harmful chemical laden products, because there are several effective ways to thicken hair naturally!

Why is Thinning Hair so Common?

Over 60% of women have thinning hair or are dealing with some type of hair loss.

There are many health conditions and simple vitamin deficiencies that can cause hair to thin or thin hair may just be a genetic trait in your family. To treat thinning hair it is best if you can find out the cause. However, even if you don’t know the cause, there are many natural ways to thicken your hair that are very successful and simple to do. You can see results in just a few weeks to a few months!

Causes of Thin Hair

There are many causes that could be the reason you have thin hair or are experiencing hair loss. Listed below are just a few of the most common causes. In order to determine the underlying cause, you may want to see a Naturopathic doctor who can help you by getting appropriate blood tests to find out why your hair is thinning.

-Shampoo: If you’re shampoo contains harmful ingredients such as sodium laureth sulfate, which has been linked to causing hair loss, switch to a natural shampoo immediately. Castile soap makes a great all natural shampoo (see it here).
-Copper Deficiency- A deficiency in copper can cause hair thinning and other symptoms such as fatigue. A lack of this mineral is common because it can be difficult to absorb and those who supplement often with zinc, have even more trouble absorbing it. Women who supplemented with cooper saw an increase in hair growth by 38%.
-Manganese deficiency- German researchers found that some women were deficient in this mineral and those who took 10mg daily re-grew their hair in just 3 months.
-Hypothyroidism- One of the most common symptoms is hair thinning. This is easy to check with a simple blood test.
-Vitamin D Deficiency- Hair loss is one of the primary symptoms of a deficiency in vitamin D.
-Hormonal Imbalance- A disruption in the balance of your hormones, such as estrogen or testosterone can cause hair loss.
-Stress – Due to increased cortisol levels, stress can cause hair thinning and hair loss.

5 Ways to Thicken Hair Naturally

1. Castor Oil:

Castor oil has been used successfully for many years for increasing hair growth, not only for your head, but also for eyebrows and eyelashes. It is well known for the many health benefits it provides including its anti-inflammatory, antibacterial and anti-fungal properties. Castor oil is high in omega 3 fatty acids, ricinoleic acid, and vitamin E, in addition to many other minerals and proteins. These nutrients help nourish the hair and scalp to increase growth. Castor oil also increases circulation, which is critical for promoting hair growth.

How to use it: Take a few tablespoons of castor oil (use more or less depending on how long your hair is) and massage it into your scalp. Make sure to use pure castor oil that is hexane free, like this.

It is a thick oil so it may be a little difficult to spread. You can mix it with a thinner oil to make it a little easier to put on, like coconut oil. (Just mix 1/2 coconut oil with 1/2 castor oil). Continue to massage it into your scalp for several minutes, then begin to work it through the rest of your hair. Let it sit on your hair for an hour or two, then wash it out. Try to do this at least once a week or several times a week for better results.

2. Onion Juice:

Onion juice increases circulation and decreases inflammation of the hair follicles, which promotes hair growth and decreases hair breakage. The onion juice also acts as a natural antioxidant to reverse the damage caused by a buildup of hydrogen peroxide on the scalp, which is associated with hair loss.

See how to make onion juice and how to use it to thicken hair naturally in my post, here.

3. Ginseng:

Applying ginseng to treat thinning hair works because the beneficial compounds it contains help stimulate blood flow to your scalp and hair follicles, which aids in the regeneration of cells to promote hair growth. I use these American gingseng capsules. I empty the capsule and mix it with oil to make it easy to apply.

How to use it: Empty one ginseng powder capsule and add it to 3 to 4 tablespoons of oil (you can use coconut oil or jojoba oil). Stir the mixture and apply it to your scalp. Continue to massage it into your scalp for about 5minutes. Repeat several times per week or daily.

4. Massaging Scalp:

One of the simplest ways to promote hair growth and reverse thinning hair is to just to massage your scalp daily. Massaging your scalp increases blood flow and promotes circulation to stimulate hair growth. Just use your hands to massage your scalp for about 5 minutes, two times a day. I do it once in the morning and once at night.

5.Essential Oils:

There are quite a few essential oils that have been shown to promote new hair growth and prevent hair breakage. Two of the most common that are used to increase hair thickness are: grapeseed oil and cedarwood essential oil. Grapeseed oil contains a high amount of essential fatty acids and Vitamin E which promotes thicker hair. Additional beneficial essential oils include lavender, rosemary, and thyme.

How to use it: Add 5 drops of one of these essential oils to 2 to 3 tablespoons of a carrier oil (coconut oil or jojoba oil works great). Mix them together and apply to your scalp with your fingers. Continue massaging it on to your scalp for about 5 minutes. Repeat several times a week.

2 Ways to Make Your Hair Look Thicker Instantly!

If you start using some of the above mentioned ways to thicken your hair, you should see results in a few weeks or within a few months. But, if you want your hair to have more volume and look thicker instantly, there are two natural ways to do it.

1. Baking Soda-

Instead of washing your hair with shampoo, use baking soda. Typical shampoos leave behind residue that builds up on the hair shaft and can leave your hair flatter, more dull, and looking thin. To wash your hair with baking soda, take a 3 to 4 tablespoons of baking soda and add about 3/4 cup of water. Mix them together and it will form a liquid mixture that can be used in place of shampoo.

The baking soda removes the build up of residue and will instantly leave your hair looking thicker. With continued use it also works great because it stimulates the hair follicles and the exfoliation it provides can boost hair growth over time.

2. Apple Cider Vinegar-

After you wash your hair, take 1/2 cup of apple cider vinegar and pour it over your hair as a hair rinse. Do not rinse it out with water, leave it in your hair and dry as usual. The apple cider vinegar is full of nutrients and it helps balance the pH levels of your scalp. After you dry your hair you will see it will have instantly more volume. This is because the vinegar removes the build up of residue on your hair.

Not only is apple cider vinegar great for adding volume to your hair instantly, but with continued use it will also promote hair growth and decrease hair breakage due to its rich source of vitamins and nutrients.

Have you tried any of these ways to thicken hair naturally?

    I think my hair is genetically thin, inherited from my grandma and mom. And it grows pretty slow. I try to do hair masks with coconut oil, olive oil, aloe vera, cinnamon, I even used onion (but it stinks so bad I don’t think I’ll do it again). I started taking biotin, which actually seemed to help prevent hair loss. I will consider manganese and copper. Thanks!

    • Lori Klein says

      Glad to hear it’s helped prevent hair loss. The onion is hard to get used to, but so many have seen great results from it :)

  2. Cindy says

    What about natural grass-fed gelatin? No mention of it here, but it’s great for thick, pretty hair.

    • Lori Klein says

      Grass-fed gelatin is fantastic! Thank you for mentioning it! I was trying to stick with more topically treatments, but dietary changes are extremely important as well. :)

  3. Robin Conkel-hannan says

    I tried the sodapoo but it dried my already dry hair.. I had been using 50/50 ACV and honey for hair loss.. I realized that it was also cleansing my hair.. After I rinse the mix from my hair I follow it with a vinegar rinse and with a bit of coconut oil.. My hair is the best it’s ever been..

    • Lori Klein says

      Thanks Adrienne! I use castor oil about once every two weeks or so. It was hard to get out for me too! But, I apply a little baking soda afterwords and really helps get it out. :)

  4. says

    Alma naturals makes shampoo bars with essential oils. My husband uses the one for thinning hair and his hair is growing back. I use the one for dandruff. My daughter with oily hair uses the orange mint and my daughter with waist length hair uses the lavender and frankincense one. Willi never go back to liquid shampoo. I only condition my hair twice a month. The bars have argan oil coconut oil jojoba oil and olive oil.

  5. dee leatherman says

    How would I use the grape seed oil for my thin hair also I have Walmart organic extra virgin coconut oil will that work

    • Lori Klein says

      Coconut oil works great it is very moisturizing! You could mix some of the grape seed oil in with the coconut oil and apply it as a hair mask.

        • Lori Klein says

          Avocado oil is great! I’ve used castor oil, coconut oil, and jojoba oil before. Oh and olive oil. :) Just a few teaspoons is usually enough.

  6. E Pyer says

    Baking soda to get out residual castor oil. Can you explain. Make paste or put straight on head? Will any of this affect semi-permanent hair color?

    • Lori Klein says

      I pour a couple tablespoons of it dry into my hand and rub it near the roots of my hair. (You may not need to use that much- I have really long hair) Then put my hair under the water and massage it while I’m rinsing it out. It takes out the extra oil. :)

  7. Zulfi says

  8. Tania says


    Has any of these natural remedies actually made your thicker? If so could you let me know which were most effective? I lose quite a few strands of hair when I’m in the bath tub and I get scared that I will lose my hair.

    Thanks :)

    • Lori Klein says

      For me, I’ve noticed a big improvement from doing the massaging (2 times a day for the past few years), castor oil (weekly), and doing the onion juice.

  9. Jitendra says

    I am 42 year old men.from last few years i lost my hair very fast.pls. suggest me best to stop hair falling,thinning and grow new hair.

    • Robin Conkel-hAnnan says

      ACV/honey mix, 50/50 works well for me.. I don’t think there is help for male pattern baldness as it’s hereditary..

  10. none says

    I am a Guy and I want to thicken my hair, slightly. Would hyaluronic acid help? I eat a healthy diet. My hair used to be blonde, somewhat now it isn’t…what happened? Hormonal change, I think so. I intend to keep my hair forever so do you have any advice?
    You can email me back, if you want to.

    • Robin Conkel-hAnnan says

      All of the changes you mention can be the result of aging.. They can occur in some people who are quite young.. Darkening of hair can occur up to 30 or so.. Lightening/fading usually comes with late middle age.. I had an aunt who’s red hair turned brown, in late middle age..

  11. Shorya says

    My hair already have immense power to grow quickly but the one and only problem I’m suffering through is my thin hair!!!! Hardcore solution required soon ??

  12. sooniu says

    i have oily should i avoid oil massage or use it?if i should use which oil? my hair is falling a lot and now its too thin. is it bcoz of oily hair.what can do

    • Lori Klein says

      You can still use oil even though you have oily hair. Sometimes hair becomes oily because we are washing it too often and stripping away the natural oils.

  13. says

    Hy i extremely need your help. Please tell me can I use baking soda to thicken my hair? Does it also reduce hairfall.? What is cider? My hair are very thin and it is falling a little but I feel embarrassed of my thin hair. What should I do?

    • Lori Klein says

      I’ve used all of them over the past few years and the ends of my hair are color treated. They still came out good and didn’t harm my hair.

  14. Riyaz says

    Hi, I am 48 yrs, male n m going bald and my hairs are thin, can you suggest something for me, will castor oil with jojoba oil help regrowth? Thanks

  15. says

    Does baking soda make hair dry and brittle. Can anyone having already dry hair can use it? Can egg also make volume in hair and what vinegar should we use white or green

    • Lori Klein says

      I use apple cider vinegar after baking soda, it acts as a natural conditioner. Egg works great for shine and moisturizing.
