      Pre-pooing Before Shampooing: Is It In Vain?

      Shampoo and conditioner aside, any product you place on your hair is going to coat the strands and cause buildup. Why do we shampoo our hair? We shampoo our hair to get rid of buildup in our hair. For some, shampoo can be too stripping.  Unfortunately, stripping can take away the hair’s natural oils leaving […]

      5 Ingredients You MUST HAVE In Your Hair Conditioner

      5 Ingredients You MUST HAVE In Your Hair Conditioner

      What are Conditioners? Hair conditioners are applied after shampooing to restore moisture and protein back into the hair shaft. Although, unless a conditioner contains small enough compounds or humectants, very little of it will actually enter into the hair shaft. This is why it is important to read the labels on your conditioner to make sure your not just […]

      Using Heat with your conditioner on Natural Hair

      Using Heat with your conditioner on Natural Hair

       I have read plenty of articles and seen many videos where people write and talk about 'opening'* the cuticle to allow ingredients in hair conditioner to penetrate. This is supposed to be a key principle as to why you should pick a product labelled as a deep conditioner and also a reason to use increased heat when conditioning (wrapping conditioner soaked hair with a towel or using a hair dryer).  Let me explain why the concept of 'opening' the cuticle is junk science.

      1. It is damaging to cycle between raised and smooth cuticles (or open and closed)

      Scientists have observed that when a lock of hair is cut and preserved in a jar, it simply does not suffer the same wear and tear that hair which is on your head suffers. This is because it avoids being washed and the subsequent swelling that can impact the cuticles and cause them to chip away. The strands also are not brushed or combed, again preserving the cuticle.

      Raised hair cuticles are common in relaxed or bleached hair and are in part the reason why these processes can make hair more fragile and susceptible to damage (Journal of Cosmetic Dermatology, pp 180-185, 2003).

      I would never regard a raised cuticle or 'open cuticle' as a positive. It is necessary and unavoidable for example you may need to wet your hair to moisturise it or you may use shampoo to cleanse your hair. Both of these actions do slightly swell and raise the hair cuticle . However, this is the reason why hair conditioner exists, to fix this problem (and it is a problem) of raised cuticles. This is also the reason why coconut oil as a prewash can help you have less damage.

      2. The first action of hair conditioner is to smooth ('close') the cuticle.

      Human hair naturally has a slight negative charge and this increases further when hair is shampooed as shampoo contains surfactants with a negative charge. This has the effect of raising the cuticle slightly. Hair conditioner immediately acts to counteract this because it contains positively charged (cationic) surfactants. This action happens rapidly within seconds.

      Therefore, your hair will not be seating out there with raised cuticles waiting for substances to penetrate. Substances that can penetrate hair (see this post), do so because they have the right chemistry, i.e size, shape, charge and/or flexibility, to be able to get underneath the tiny space of a smooth cuticle. They do not require an 'open' cuticle to penetrate.

      * As a general note for those who are new to the blog, I do not like to use the term open and closed cuticles although these are terms widely used in the natural hair world and I am certain many of you understand what they mean. The cuticle really does not open, what it does do is raise itself from the surface. In place of open and closed, I use the terms raised and smooth. 

      Conclusion: You do not need to and do not want to 'open' your hair cuticles by force. It is unavoidable if you wet your hair or use shampoo. Hair conditioner will 'close' the cuticles and protect the hair from damage. Using heat is beneficial not for increasing swelling of hair or 'opening' cuticles but rather for allowing more conditioner to stick on the surface of hair (aDsorb) - see this post

      For advanced learners:
      1. Technically not all shampoo will cause the cuticle to be raised. Shampoo with non-ionic or zwitterionic surfactants do not have this effect (Mild Shampoo list, In detail - charge and shampoo)

      2. If you are wondering, here are examples of cationic sufactants found in hair conditioner: stearalkonium chloride, cetrimonium chloride, dicetyldimonium chloride, behentrimonium methosulfate, behentrimonium chloride, stearamidopropyl dimethylamine, etc.
