The Theory of Castor Oil and Hair Growth

There are speculations, claims, and detailed research on the benefits of castor oil to hair growth. While castor oil is good for hair, does it help in hair growth?

Although it has been claimed that castor oil hair grows hair, there is no scientific backing or evidence to prove castor oil directly influences hair growth.

This creates a conundrum, because it has been proven to have nutrients and properties that aid hair growth, but not the actual growing of hair.

According to board-certified dermatologist Dr. Sheel Desai Solomon, “The scientific evidence surrounding castor oil growth is lacking.

“It does, however, enhance and increase the absorption and effectiveness of other products,” she finishes.

Board-certified dermatologist and Residency Program Director at The George Washington University School of Medicine and Health Sciences Adam Friedman, M.D., FAAD, supports this too.

“While castor oil does have antimicrobial properties which may be useful to the scalp, there is zero evidence that it is helpful to hair growth,” he says.

Nevertheless, this does not disprove the fact that castor oil is good for hair. Therefore, if you want to use castor oil, you will certainly be getting healthier hair, moisturized strands, and defined hair curls.

Moreover, if the right conditions are set with castor oil, your hair has a better chance of growing. As a result, there is no reason not to use castor oil if you want hair growth results. Notwithstanding, this should be paired with the right hair routine to keep your hair in a healthy and growing phase.

According to board-certified dermatologist Rachel Nazarian, you need to use castor oil in moderation due to its thick consistency. Although it is safe to use, excess oil in your scalp could build up residue and block your roots. This, in turn, stops oils from flowing freely in your hair.

You can use castor oil for the following hair routines:


If you have extremely dry hair, you should start with pre-pooing your hair if you need hydro-boost. In addition, this gives your hair the needed moisture and coating to prevent shampoo from stripping your hair off.


  • Section your dry hair.
  • Coat each sections and subsections of your hair with appropriate amount of castor oil.
  • Only coat your hair with a thin layer of castor oil.
  • Massage and gently detangle your hair with your fingers.
  • Finally, use shampoo to wash the excess oil and grime off your hair.

Your hair would retain some oil after shampooing, thereby retaining moisture in your cuticles.

You can use castor oil for hot oil treatment. The steps are easy and do not require too many tools. Hot oil treatment helps extremely frizzy hair that needs moisture.

It is also used for thick and dense hair. The hot oil easily slips through thick and dense hair.

  • Section your hair.
  • When the oil is warm, apply it on your scalp; it should be mildly warm so it can sit on your scalp.

  • Leave it in to absorb; wait for 20-30 minutes.
  • You can use a plastic wrap or a shower cap to cover and preserve the heat for as long as possible.
  • Rinse off the oil.

Dry scalp treatment
