Rapunzel had it, we all want it!

Ever wondered why your hair grows? and how it grows? I loved studying the "science" side of hair and the different stages we encounter with our locks.

Your hair goes through three growth stages, Anagen, Catagen, Telogen and depending on when your hair reaches the stages, and how long it stays on the stage (anagen stage particularly) depends on how long your hair gets.

Anagen is the main growing stage, this can last from a few months to a few years.
Catagen is when the hair stops growing, and slowly starts to seperate.
The final stage is Telogen, where no growth occurs. This is the shortest stage lasting from a few hours to a few months. However if this stage continues, baldness occurs.

Obviously certain factors will affect your hair, the environment, chemicals and your health. Environment wise, living in a built up area will mean your hair is subject to pollution, and likewise living by the sea mean salt in the air has the same effect. Chemical wise, colouring your hair, along with perming/relaxing can subject your hair to all sorts of damage. Tints less so, with bleach coming higher up the damage chart. Finally your hair, I've often spoken of the fact you need a good diet full of nutrients to help give your hair the best start, it all comes from within. Products can help, and I've spoken about them in the past, but doing all you can to help your hair makes sense.

So, if your hair grows like a weed, blame your catagen stage for getting stuck. 

And if it is stuck, I'm very jealous. :)

Do you think it's nature or nuture on hair growth?
