Make thick hair thinner in the comfort of your own home by applying a conditioner after shampooing. Rinse with cool water. Towel dry and apply a leave-in conditioner. Comb through from shaft to ends. Blow-dry hair till almost dry, then use the cool setting. Finish with a flat iron.
Ask a professional stylist to help thin your thick hair. Get long layers cut into your hair with thinning sheers or a razor. This helps eliminate the top layers of hair that may be frizzy. Get a salon blow-out that straightens hair and lasts for days. Indulge in a special keratin treatment that lasts for weeks.
