The skin is the body’s largest organ and is one that constantly replenishes itself. It consists of 4 layers, with new cells being created at the lowest layer and the uppermost layer being continuously shed. It takes approximately 25 to 30 days for cells from the bottommost layer to be shed. These microscopic flakes of skin which are continuously being shed are called ‘squames’.
Your scalp is made up of skin too but it has some slight differences. For starters, it is home to the most number of visible hairs on your body- anywhere between 100,000 and 150,000 if you actually counted them. Your scalp also secretes a lightly greasy substance called sebum. This sebum is nothing but your scalp’s natural defence system against microorganisms that would love to live in your hair which is an ideal environment for them.Reasons for Dandruff:
Sebum is pretty effective. However, one fungus, Malassezia has adapted to live off sebum. This organism releases oleic acid which deposits on the scalp. Oleic acid can speed up the shedding process immensely, as quickly as seven days in extreme cases. So the skin that is shed clumps together and forms what we call dandruff.
We see an increased amount of dandruff during puberty because that is the time our bodies start producing an increased amount of testosterone. Testosterone has an increased effect on the production of sebum and this causes increased dandruff. Check out 10 home remedies for dandruff with ingredients easily available at home.
Your scalp is pretty efficient at looking after itself but it does occasionally need the help of a good anti dandruff shampoo like Head and Shoulders shampoo to neutralize the effects of Malassezia. Use one at regular intervals to take the fight to Malassezia and curb dandruff.
