I loooooooooove stretching, once I figured out how. For me, it requires
frequent cowashing and wet bunning. Earlier on (for the first 8 weeks or so) I can do wet sets with no problem.
From week 8 - 15, I need to cowash almost every day. I leave in Redken Butter Treat and wet bun without combing. This keeps the ng soft and PREVENTS breaking.
I only comb once a week. I tie the roots down with a silky scarf and my hair is crinkly but lays flat down. I don't even need jheri curl juice -
completely wetting my hair daily keeps it soft.
I agree that the issue is retention, so I moisturize my ends twice a day. I also get a trim 4 times a year to prevent splitting.
I stretch out of necessity - my hairdresser is 3 hours away, but my hair has completely turned around in thickness and health. I am double processed - relaxer and bleach, yet my hair has grown from above APL to almost BSL. I have been stretching now for over a year and the results are worth it IMO.
