My top tips for hair growth and length retention 1. Wash your hair atleast 2 times a week. I use Redken all soft shampoo and conditioner. 2. Use a deranging spray that has a heat protectant built in. I like the redkin acidic bonding spray. 3. Let your hair air dry to about 80% before blow drying 4. Sleep with your hair contained (loun, braid, bonnet, etc) 5. Get regular trims (every two months is what | do) 6. Use a wide tooth comb to comb when wet 7. If you are going to color your hair, do a color that doesn't require bleaching the hair 8. Use an overnight treatment in your hair at night. I like the Kerastase overnight treatment. I have used it for years. 9. Do not put grease on your scalp. It blocks the hair follicle. 10. Don't use shampoo that has protein in it. hair hairtok longhair lengthretention healthyhair LTKOver40
