Keeping Control of coarse, thick hair

Wash
Coarse, thick hair is often drier because it has the least amount of oil glands and the largest diameter. The good news: it means you can go the longest between shampoos. Wash once or twice a week, and make sure you lather twice if it's been a whole week between shampoos. Use something labeled as moisturizing; ones that contain oils like jojoba, coconut, or argan, which sink in and restore moisture

Cut
Get a cut every 12 to 16 weeks, and at every other appointment, ask your stylist to remove bulk from your hair. Doing it at every appointment could make your hair look and feel too thin. Also, try to keep it on the longer side. Styles that are shorter than shoulder length require more maintenance in a daily styling routine, as this texture looks best smooth and shaped.

Color
Coarse hair tends to be naturally dark, so regrowth can be very noticeable. Color as often as you need to"”every two to four weeks if you have severe grays, or every six to eight weeks for highlights. If you're using a semi- or demi- permanent formula, pull the color all the way through to your ends every time to get a boost of shine. Keep in mind that coarse hair can be very dry, so incorporate a hydrating mask into your regular routine to prolong your color's vibrancy.

Style
Heavier styling creams are your best bet. Start with a dime-size amount and add more as needed. This will help add moisture and shine and also define the texture. This type takes forever to dry and style. Fake a blow-out by showering at night and twisting damp hair into a high bun. In the morning, undo it, and wind a half-inch iron through a few front and side sections. Set with hair spray.
