after 3.5 months I would change my normal regimen... ( I wear weaves too)
-pre-poo w/ oil before removing braids
-take down braids and DETANGLE, DETANGLE, DETANGLE,
-put hair back in braids, then clarify shampoo, moisturizing shampoo (one braid at a time then rebraid)
-condition hair w/ protein treatment (in braids)
-DC hair with moisturizing treatment (in braids)
- apply leave-ins and wear protective style for a week or two, then back up into a weave, relaxer, etc.
The oil at the beginning step, detangling and the braids are the key. I've had to detangle my BFF hair for 2-3 hourse b/c she kept a weave over 3 months and shampooed it and it all tangled up. She was going to have to cut her hair off but I applied every product I had to loosen that stuff up!
