Well, those dandruff flakes are not only embarrassing, but can cause hair breakage.
What's weird about the dreaded snow drift is that sometimes you see it and sometimes you don't. I can wash and moisturize my hair and not see the flakes for months and then on another day right after I wash my hair, the snowflakes, salt and sugar are falling all over my head. While I know to use a good medicated shampoo, what I didn't know is that hair breakage can also occur.
According to dermatologist Dr. Zoe Draelos, a clinical associate professor in the department of dermatology at Wake Forest University School of Medicine, what causes dandruff is an airborne fungus called malezzesia globosa. The name even sounds diabolical. Because this fungus is airborne, a cure is impossible. However, we do know how to treat it. So wherever you are and if there is air around, you can get it.
Now the breakage becomes a factor when you are itching your scalp. Remember all the cuticle layers that protect the cortex?--
See a picture here and find out what part of the hair is damaged, when you're itching because of dandruff.
If you scratch your scalp, you can take off all of those cuticle layers from your hair strands which can break off your hair.
Along with hair growth, scalp health is important too. Growing long hair is also growing clean and healthy hair so malezzesia globosa doesn't stand a chance.
