So I didn't make it to 20weeks post. However, I relaxed my hair at 19 weeks post relaxer. I think we are getting better at relaxer stretching *big grin*
I started by detangling my hair the night before relaxer day. I Sectioned my hair into 4 and sprayed some detangler (Mane n tail detangler) to each of the four quadrants and detangled gently, a section at a time. I used my fingers first and then used a comb.Detangling wasn't much of a hassle for me but I had mostly clumped strands which I separated gently Then the next day I followed my relaxer routine which you can findHERE Application and smoothening took me 15minutes.
