How Ceramides Benefit the Hair

How Ceramides Benefit the Hair


Ceramides are a type of lipid which is a natural component of the hair cuticle. Just as a refresher on the anatomy of the hair, the cuticle is the thin outermost layer of the hair that serves to protect the hair shaft and provide strength. The cuticle is made up of a number of dead cells which overlap each other and resembles the shingles on a roof. Understanding the anatomy and purpose of the hair cuticle will help in understanding the role of ceramides play and how they benefit the hair. In an effort to make the information regarding ceramides as clear, understandable and concise as possible I decided to present it in list form. All of this information is based on the results of published scientific experiments and the references are listed at the bottom of the post for your convenience. Enjoy!!!

Role of ceramides:

  • Hold the scales of the hair cuticle together, which in healthy hair results in smooth and lustrous hair. In damaged hair, the ceramides are missing and results in dull, coarse and dry hair.

Benefits of Ceramides:

  • Application of natural ceramides to damaged hair improves the scale of the hair cuticle and restores the natural properties of the hair.
  • Application of products containing ceramides (synthetic) results in decreased breakage to relaxed hair (as shown in hair treated with guanidine hydroxide, aka no lye relaxer)
    • Ceramides are most beneficial to relaxed hair according to a study done by L’oreal. For more information on how they determined this and why relaxed hair benefits most, please check out this amazing post by The Natural Haven.
  • Application of synthetic ceramides (which is more concentrated than natural ceramides) to damaged hair produces immediate improvement in the strength and appearance of the hair.
  • Reduces the friction coefficient of hair. By reducing the friction coefficient, ceramides reduce hair damage caused by abrasion and daily weathering.

Other Facts Regarding Ceramides:

  • A study on hair damage was attributed to the loss of ceramides and other intrinisic lipids of the hair (study examined hair that was damaged specifically by hair bleach).
  • Ceramides are only deposited in small amounts into the cuticle layer of hair, yet they are effective in improving the hair’s condition.
  • In skin, ceramides have shown to decrease water loss; however I did not find any studies that showed that indicated it had the same effect in hair but that does not mean that it doesn’t help with moisture retention in hair either.

Oils That Contain Ceramides:

  • Hemp seed oil
  • Wheat germ oil
  • Rice Bran Oil
    • I know all of the above oils definitely contain ceramides from my own research. However, other bloggers have provided much more extensive lists of not only oils but other hair products that contain ceramides. One of those products is Aubrey Organics White Camellia conditioner, for which I can personally attest is an amazing conditioner.
    • Check out this list posted on From Short to Long, which also includes her brief take on ceramides.
    • Although you know I prefer all natural products, synthetic ceramides are actually shown to be more concentrated than the ceramides that occur naturally (such as in oils). In this sense, non-natural products may actually be more beneficial. L’oreal, for example, has a complete line of products called Elvive Damaged care which contains a high amount of very concentrated ceramides.

Additional Reads on Ceramides: I strongly encourage you to check out each of these blog posts, they are exceptionally well written and provide sources for their information should you want to do additional research for your own knowledge. It looks as though all of the authors (including myself) used many of the same resources but each of us provide a different perspective on ceramides.
