Consider stopping chemical relaxer, color, or heat for 6-12 months Place a hair weave that is not tight and will allow scalp care Loose braids Wig Natural hair but do not straighten with heat Serial trimming of hair (every 6-8 weeks) Use heat protectant products on the hair before styling Layering moisturizing regimen Start with moisturizing shampoo and conditioner (should state for dry, damaged hair) Next apply a leave-in conditioner with coating agents to wet hair (dimethicone-coating agents) Add a leave-in conditioner (oils) to dry hair (after washing weekly and then as needed daily) Discuss the long wait for improvement 66 33
