I went into hairdressing on leaving school, after 5 years training I was a salon owner, After that I was teaching hairdressing levels 1 2 3.
I am not sure if your condition is related to PD or not. As you normaly have greasy hair and scalp when you are going though puberty. Any way try this when you wash your hair don't massage your scalp, use a light conditioner to close your cuticle. Always comb your hair never brush it, as this will make your sebaceous gland produce more sebum (oil) When you dry you hair always use a product so the heat of the dryer doe;s not dry your hair out too much, you still want a little oil there. Use blowdry spray in stead of a moouse. Always use a good product Wella, L'oreal Clairol ect. I hope this helps.
