The curl pattern for 4A hair is a S-shaped coil you could wrap around a chopstick. Regardless of how thick or fine it is, almost all type 4 hair is fragile. Perhaps the most fragile of all the hair textures.
If density is fine think REPAIR-ME.WASH & REPAIR-ME.RINSE, and using RE.STORE as a treatment or co-wash works well.
To control frizz use YOUNG.AGAIN DRY CONDITIONER for a refresh and BEDROOM.HAIR to help you pump up your curls if they’re fine, all without the weight.
This hair texture is perfect for wash and wear styles and it becomes more about balancing moisture and humidity. You want to seal moisture in while keeping humidity out. Try using RE.STORE followed by EASY.RIDER for thicker hair. For fine hair YOUNG.AGAIN is your best friend. Believe it or not SUPER.GOO is an amazing way to hold curl and moisture levels in the hair. It goes on easily and can be left to naturally dry.
As type 4 hair is very fragile, if you heat style you need to always use HEATED.DEFENSE.
