What to do about coarse hair...
Use a mild shampoo to wash you hair with. I find that conditioning with LeKair Cholesterol Plus keeps my hair soft. Other products that keep my hair soft are S Curl No Drip Activator Moisturizer and Blue Magic Coconut Oil grease. After washing your hair, plait or twist it up so it can hold in moisture. Don't let your hair airdry loose. I also find that my hair is more coarse if I don't plait or twist up my hair. If I did daily co-washing and wore my hair out in a shrunken fro, my hair would turn out dry and sometimes crispy by the end of the day. The only styles that work for me as far as keeping my hair soft and moisturized are two strand twists, cornrows, and picked out afro puffs (surprisingly).
HTH!!!
