Stop using those No Lye Kits, they are your problem ... they over expose and under process your hair causing it to dry out and thin around the edges. Try my Mild Relaxer kit Sensitive Delicate Relaxer, Calming Neutralizing Shampoo, Revitalizing Conditioner (leave 10-15 mins rinse) Set or wrap your hair using Moisture Silk Mousse mixed my Leave-in Conditioner.
To regain your hair take the B-Natural Hair Vitamins (2 a day) and dot Root Therapy Scalp Stimulator on your scalp once a day and massage. It will help stimulate more blood circulation to your scalp and provide your hair with the necessary nutrients to grow strong thick hair.
