1. Wash your hair every other day: Or even better, try to only wash your hair three times a week if you dare. Washing your hair too often can strip away protective oils that keeps your hair shiny and healthy. If you have trouble with your roots being too oil, a good dry shampoo will take care of that and absorb your excess oil.Your hair will adjust eventually and not be so oily.
2. Cold water: Wash your hair in cool to cold water. It will help to fight frizz and close your hair cuticles which resemble roof shingles. The cuticles will lie flat when splashed with cold water. the smoothed cuticles reflect more light, making hair appear shinier and healthier (hot water leaves it rough and lackluster.) To keep the look, you want to seal it with a silicone-based serum. Some good options are John Frieda, Fekkai Glossing Cream, Living Proof.
3. Dry your hair carefully: After you get out of the shower, gently squeeze excess water from your hair and pat dry with a soft towel. Don’t rub or massage wet hair with a towel. Spray with leave-in conditioner. Comb your hair with a wide-toothed comb to work through tangles. Try to let your hair air dry as much as possible.
4. Use a leave-in conditioner: After you get out of the shower, and before you brush out your hair, spray in or rub in your leave in conditioner to avoid ripping through your tangles and creating strands to break off. Some good choices are Bed head, Paul Mitchell, Sexy Hair, or Kerastase.
5. Don’t use heat: This can be difficult, but essential if you want your hair to grow strong and thick. Try using non-heat tools to style. For example, sock bun curls, non-heat curlers, pillow curlers, braids, and air drying with some homemade sea salt spray for beach wavy look.
6. Blow dry your hair gently: If you do blow dry your hair, use a cooler setting. Be sure to always use a thermal protectant on your hair before styling with heat. Blow-dry with a nozzle attachment, keeping the airflow angled down the shafts to smooth the cuticles. Some good thermal protection options, Chi, Alterna Bamboo, John Frieda.
7. Avoid chemicals: Try to avoid hair dyes, relaxers. If you must dye your hair try henna. It can do a great job without killing your hair.
