Otherwise, the split may travel backwards to the root. Avoid tight hair styles or elastic hair bands. Do not use heated, spiked rollers frequently and never hold the hair dryer too close to the scalp (at least 15 cms away). Never use sharp combs or brushes. Never brush or comb when the hair is wet and always use a towel to dry it gently. Avoid over-zealous scalp massage or brushing.
