I'm glad you posted this because I'm a 4a/b and I stretched to 12 1/2 weeks the last time. I don't comb my hair except for wash days and daily moisturizing/sealing was fine but I encountered the most trouble while washing my hair. I took Lonei's suggestion of washing my hair in braids and it worked. My hair is fine and not thick but it's armpit and the ends started to get tangled while washing after week 8. I lost a TON of hair
during my week 9 wash and detangling was hell even though I had the full arsenal of s-curl, giovani, etc. After that fiasco I decided to detangle my hair with my hands and a large comb BEFORE I washed (I didn't comb through the roots) in about 6 braids with diluted CON shampoo (the one with the green writing). That shampoo is the most detangling IMHO because I normally use Aveda or Elucence but they ain't have jack on that CON. The braids loosened up during the wash but it was all good because the sections were already formed. I also switched up my conditioner at that point and used Silicon Mix to deep condition. I applied the Silicon Mix and slightly detangeld and loosely rebraided it and sat under the dryer to deep condition. When I got back in the shower I combed the conditioner through under running water in sections and I also followed up with Elucence Conditioner kind of like a final rinse (I wasn't taking any chances). I still shed some hair but it was NOTHING like what happened during the prior wash. I a
lso think the key to not getting tangles is to make sure you try to keep your hair hanging straight while washing but especially while detangling/washing the conditioner out. I believe this is especially important for anyone who has hair that hangs below the shoulders and down the back because that's such a far distance from the new growth and a person's head in general. The 4 a/b new growth coils up tight but there's still all that length remaining. Well, this is just my opinion and my experience but hopefully it can provide some assistance.
