Hey Sly! Well... let's see. For me, my halo hair is straighter than the rest, and relaxes very easily in a short amount of time (except for the very tip of my nape which cannot be even classified and I could probably leave the relaxer on from sun up to sun down with no damage
). Anyhoo, all of my halo hair is healthy.
Now what I got from you is that most of your hair is 3c, and you like its texture, but the front halo hair is bushier and does not lay smooth. My mother's hair is like that too. I also once saw a biracial girl extremely fair, with blonde hair that was 3
b all over with
4a halo edges in front. If that had been my child, I would have relaxed the front halo
only, cuz the difference in textures was enormous. In my mom's case the difference is not as extreme so she can get away with other techniques like wetting that front, add a leave-in and a dot of gel, and tie down with scarf till smooth.
So my advice is this: If you like your 3c texture, then don't relax all of your hair. I would use other techniques to deal with the halo or straighten it with a relaxer. If you relax this part, keep on the min of time, and do extra things to care for that part of your hair.
If you want to wear all of your hair straight all the time and forget your 3c texture, then relax all of it. (But I would prefer the first option if you can get away with it). Hope this helps!
