Q: I’m transitioning, and I’m finding it hard to keep both textures happy at the moment. I understand why some of us get frustrated and do the “Big Chop” only a few months in, but I’m not ready for that yet. My new growth is really moisture thirsty, but the relaxed ends aren’t. Ideally, I’d like to wash/wet my hair everyday, but when I comb my hair while it’s wet, I’m getting too much breakage from the relaxed part. How can I minimize this damage? I’d like to hang onto the relaxed part until I’m ready to part with it. I can see it’s thinning already. My hair is thick and coarse. I also have to use a hairdryer with a diffuser because my hair just won’t air dry at all.
Diane: While you want to hold on to your relaxed hair, it is really not benefiting your style or length if it is breaking. Transitioning can be tricky! However, you should not try to wear the wash and wear look quite yet, unless you are prepared to part with the relaxed hair. Wetting the hair every day with water can dry out the hair more than anything else. Try misting the hair with a leave-in conditioner like,
Jane Carter Solutions Revitalizing Leave-In Conditioner Two textures have to be treated differently at the same time. The natural texture must have conditioning treatments designed for natural hair. That means using botanical hydrating and moisturizing conditioners. Then use protein moisturizing conditioners for the relaxed hair that is breaking and shedding. This can be a quite a bit of work. You might find it much easier to finally let go. However, if you’re really not ready, you should create curly sets with rods, flat-twists or two-strand twists.Then create the twist out. These styles don’t require wetting the hair everyday, and last at least 7-10 days. There are also curly hair extensions that can help you transition easily as you wear a fabulous curly style and grow out your healthy hair.

Q: What hair options are available to 4B’s? I have a friend who wants some suggestions. I told her 2-strand twists, coil outs, and wash ‘n go are good options. Anything else?
Titi: The main styling options are 2-strand twists, coilouts, wash ‘n go and shingling. However, to add more variety, alter the way you execute each styling method. For a 2-strand twist, changing the size of the twist will give you a dramatically different look. Larger twists result in a fatter curl. Smaller twists result in a tighter curl. Or try a 2-strand twist cornrow and untwist. That will give you a totally different look.
For coilouts, try unraveling the coil in more sections to create more volume. This will change the look of a coilout.
How you apply product for a wash ‘n go changes things too. Applying more product with a more deliberate hand will result in a controlled curl. Raking product through more randomly will create a more whimsical look.
