September’s QOM- Hair growth cycle and hair care

questiontext

How can I use the hair growth cycle to help me take care of my hair? What’s the application?

Just to remind you from my blog post, the hair growth cycle is divided into three stages: Anagen (growth), Telogen (rest) and Catagen (degeneration). The majority of hairs on anyone’s head is usually in the Anagen phase. Therefore, the best way to ensure good hair growth is to make sure that you do not disrupt your hair growth cycle. This can be done by having a healthy diet. That way, you won’t prematurely shunt hairs meant to be in anagen into telogen because of vitamin or mineral deficiencies.

If that were to happen, you would get a Telogen Effluvium where you will find excessive shedding of your hair. In the acute phase, a Telogen Effluvium doesn’t last long. However, once it goes on for more than six months, it becomes chronic and you can experience significant reduction in the number of hairs on your head. So it is imperative to have a good diet, especially a good Iron intake.

Other than a good diet, and general good health, there’s nothing that you can do to speed up anagen because the body does its own thing. You can ,however, extend the anagen phase especially with hairs undergoing Telogen Effluvium. Products such as Rogaine (Minoxidil) have been shown to extend the anagen phase thus reducing hair loss from this Telogen Effluvium.

June’s QOM

Hi Doc,

I just realized that I need to find an effective shampoo for my daughter as she has been on a local swim team for the last 2 years and currently trains about 4 days a week. Can you provide information on exactly what chlorine does to the hair and the right products and treatment for “swimmers hair” ? She wears her swim cap of course, and it does help a little as her hair is never really soaked.

Chlorine is no one’s friend. It has been shown mainly in wool (and similarly in hair) to cleave the thioester bonds which bind 18 MEA (a major hair integral lipid) to the cuticle. It also oxidises the disulphide bonds in the proteins of the hair thus degrading them. This results in increased friction between the hair fibres and of course increased fragility of the hair. It can decrease the melanin in the hair causing it to become lighter over time. 

As you know the swim caps are not designed to keep the hair from getting wet. There are some that keep the hair drier than others. The best thing to do is to coat the hair with conditioner or oil or a butter such as shea butter and then place the cap on. This also doubles as a deep conditioning treatment and gives little space for the water to eat away at the hair. After swimming wash hair with a good swimmer’s shampoo. These usually have Vit C or sodium thiosulphate to remove residual chlorine. They also contain EDTA to remove copper found in the algaecides present in the pool. Copper deposition is responsible for green tinge in lighter hued hairs. It doesn’t show in black hair but the copper is certainly deposited.   Follow with a conditioner. Hope that helps!
