Next to each hair is a sebaceous gland which secrete sebum which lubricates the hair and provides each hair with an element of protection. If the sebaceous glands are overactive greasy or oily hair will result. If the glands are underactive dry hair may result including breakage.
Daily Hair Tip
To create retro-look hair waves liberally apply a good setting gel, then use massive clips to hold hair in desired shape. Use gentle hairdryer heat, release clips and enjoy lots of new waves.
