Hair loss may be one of the most common hair issues. New styling techniques with chemicals and heat are bad for hair, weakening it and increasing the chance of advanced hair loss.

There are a number of things we can do to strengthen our hair, but personally, I feel more comfortable with natural treatments like oil.

There are several oils that you can use for hair growth and hair strength but I will talk about castor oil today because it has been used as a hair treatment for centuries. It contains numerous minerals and fatty acids.

Here is when you should use castor oil for your hair:

  1. When you see hair falling out at a quicker rate than normal.
  2. When you see split ends.
  3. When your scalp is dry.
  4. When you just want healthier hair.

How to Use Castor Oil as a Hair Treatment

1. Wash hair.
2. Warm the oil on the stove or microwave.
3. Massage oil through hair and on scalp.
4. Cover hair.
5. Wash out.

Step-by-Step Hair Oil Treatment

  1. Wash your hair Some stylists suggest applying warm oil to the hair before shampooing, but I don’t recommend this. Wash your hair to ensure that it is clean before you apply any oil to it.
  2. Warm the oil Pour castor oil into a pot or bowl. If desired, add olive or coconut oil. Gently warm on stove or microwave. Alternately, place bowl in a tub of hot water. In either case, ensure that oil doesn’t get too hot.
  3. Massage If your hair is completely dry, spray to moisten. It is better to divide hair into sections. Apply oil to one section at a time and massage gently. Castor oil needs a little time to absorb, so massage continuously until you can feel that oil has soaked in.
  4. Scalp massage Hair massage isn’t enough. You need to massage your scalp too. Take some castor oil and massage scalp gently with your fingertips in a circular motion. Make sure that all the oil is absorbed into the scalp.
  5. Cover hair After massaging hair and scalp, cover your head with a shower cap for at least one hour. Allow oil to completely absorb into the scalp.
  6. Wash your hair Finally, wash your hair. Make sure to remove all of the oil, shampooing twice or three times if needed.


You might not notice results immediately after washing. For best results, follow these steps twice a week. You will see positive changes within a month or so.

Hi, this is an interesting page and string of comments and questions!

Exactly how DOES castor oil make hair grow? Does it absorb into the root or something? It is awfully thick and I had to wash my hair several times to get it out. Oh, and the smell!!! Did I buy the wrong king?

My hair is light blond and shoulder length, pretty thick but starting to thin...hope to hear how to use it the right way.

thanks so much.

Whenever I do any kind of oil mask on my hair, I use conditioner to wash afterwards, not shampoo. For me, the shampoo dries out my hair too much, or it can't get all of the greasiness out. The oil in the conditioner is able to pull out the excess oil on my hair, without completely stripping it.

Hi Riya It usually takes 4 weeks for any type of hair growth or some success of thickness. Read my other comments where I explain to take a before and after image to see if it is actually working. Contact your doctor if it gets worse.

Hi Potol - every hair type of course is different - I stopped responding to comments because this is not my post and respecting the original host. First you need to follow the advice I give and take it from there. If nothing works then seeing either an endocrinologist or a dermatologist to hopefully help in that situation.

Hello Andrea - you only heat castor oil if it requires you to. Make sure you are not using a cold base castor oil. Cold base castor oil will be labeled on the bottle, might say cold pressed or cold base. If you are not sure ask a retail associate where you can find some. Now if you prefer heated (which I don't) make sure you apply it correctly.

Hello JYOTI - if you just had your child within 8 months what you are experiencing is postpartum, during a pregnancy you hormones are sky high but after a pregnancy you will lose your hair faster than it can grow. Making it harder to take care of - that happened to me 18 years ago after my daughter. It took me 12 months to get my hair back in shape - I used mayonnaise and pure coconut juice not store bought I made it at home. Castor oil might not work since this is a hormonal issue. You have to maintain your hormones as well as your estrogen, contact your doctor to see if he/she can give advice on how to balance it out.

Hello POTOL - yes you can mix other oils BUT in this case like that was mentioned they are trying to "grow" their hair so YES it is used for growth. If you mix olive oil/coconut oil it will make the hair type that is already greasy harder to actually clean thoroughly. Meaning if you don't get all the oils out it will clog the hair follicles. Just like your skin on your face - you have to maintain dry and oily skin if not your pores will clog causing pimples/blemishes. Using 'only' castor oil is better when trying to grow hair. But of course using small portions.

Hello Nick - Hmmm I am a little skeptic on reviews, some say it works and some say it doesn't. Natural oils should work but seeing the ingredients which shouldn't have an odor and most of the comments are saying it's a horrible smell. 100% castor oil is tasteless and odorless - you can find that in a pharmacy section. When you look for it make sure you find it by the section that has laxatives yes you read that right - by the laxative section. Ask a pharmacy store clerk where you can find it. Depending on your hair type start doing your treatments and always try to give it 4 weeks to work.

This comment is for Kaysie even though I am not the original author for this article I do a little about the thinning of hair since I did go through that process. Sometimes shampoo can do that depending on the ingredients. With too much silicone can clog your follicles so hair won't be able to grow. When brushing your hair (do not comb) use a soft tip bristle brush.

When applying castor oil - since your hair is oily do a treatment once a week. Before you start treatment take an image of the area that is not forming. Make sure the castor oil is NOT warm, it has to be a cool base. Also make sure the oil is 100% castor oil and not mixed you will know when the bottle says odor free and is tasteless. Take a small amount of the oil to your fingertips not palm, make sure you place on area and move your fingertips in a circular motion (slow) for 1 minute. If there are more than one area that needs treatment do the same amount of time and movement for each. Once you have done all the areas that needs attention take a shower cap (disposable or reusable) and leave it in your hair for 45 minutes. DO NOT wash hair before applying, only after the treatment.

The best shampoo to get is the kind that doesn't have color in it. The color in the shampoo has silicone in it. I use DOVE shampoos for thin hair. It will have it on the label (for thin hair). Make sure you use the same conditioner, making a note to this when washing hair on a regular basis make sure you don't over wash or under wash. Every other day or every 3 days is best.

Hello NASRIN castor oil can do so much - what you can do is try when you apply properly and continue for 4 weeks and if some does grow then it works but if nothing happens, probably the best thing to do is ask your doctor for something that might help.

Kaysie 20 months ago

My hair has started to thin a lot. I think its because of change of shampoo& conditioner or back combing ..

I don't know how to apply castor oil to my hair & how often. My hair gets oily quite quick so i started oiling once a week, i just pour some into my hand and dab it onto the top of my head im not sure if im doing it right. Aha.

nasrin 20 months ago

Hi Sunny When you prepare don't mix it up - keep it the same preparation until you start seeing results then you can calm it down. Since you have oily hair it's best to do it once a week. Use a disposable or regular shower cap and leave it in for only 30 minutes. Wash with shampoo that doesn't have silicone added (example DOVE shampoos with no color). DO NOT wash hair before applying, make sure it's a little wet just with plain water. DO NOT over wet it just put your hands under lukewarm water and place it on your hair. Dip your finger tips or pour a small amount onto your fingertips then massage it gently in circular motions close to the roots. Since you have to do it a different way you will see results (hopefully) in 4 weeks. As long as you do it the way I explained it might actually work. Try it and let me know if it does. Remember take pictures of before and after 4 weeks.

Hi Siva, if you don't mind me asking a few questions - what condition is your hair (oily, dry,etc) . How are you preparing your hair? (wrap in towel, shower cap, etc) How long are you keeping it in your hair? Also how many times a week? Hopefully I can help you with this - I am seeing results more now that I can actually only do it once a week.

Hi Pauline - I saw your comment and wanted to see if there are medical reasons why it's not growing? But if that is too personal or you don't have medical problems then it would definitely have to be on how they are asking you to do it. It's actually wrong - don't wash your hair before applying (oil needs more oil to work) and get cold pressed or cold pressured castor oil not heated. You will know if it's 100% castor oil when it says on the label ODORLESS/TASTELESS. I have been doing this for 2 months and the results are good. My hair is super thin and now it's actually getting thicker in the front and back. It brought back my natural hair color (happy). So hopefully this helps you.
