Maintain a PermQ: How do I maintain a perm?
A: Well, the main thing to remember with permed hair is that because of the chemical treatment, the hair is most likely going to be more porous. This means that not only will it absorb moisture more quickly, but it will lose the moisture just as quickly. This becomes doubly true if you use heat styling appliances such as blow dryers, curling irons, flat irons and hot rollers.
Use a shampoo and conditioner designed to give you "smooth and sleek" hair. These formulas typically contain protein and ingredients designed to help flatten the cuticle layer and prevent frizz. Also, make sure you condition your hair every day, whether you shampoo or not, particularly with permed hair. Because of the increased porosity of the hair, things like exposure to sunlight, wind, and very dry air can leech moisture from the hair and leave it fragile.
If you must use a hair dryer, be sure to use an additional spray-on, leave-in conditioner to protect the hair, and always use a diffuser attachment on the dryer to prevent damage and protect the curls. Finally, try not to fully dry the hair using the hair dryer. If you use a styling product, you can get the hair to the point of being "mostly dry" and allow it to finish drying naturally.
Remember, too, that porous hair is more prone to tangles and matting. If you notice, frizz or tangling in the morning after you sleep, you should consider purchasing a sleeping cap or silk or satin pillowcases to sleep on. These will help protect the hair from the friction of the bedding and should leave you with smoother, easier to manage hair in the mornings.
Aside from that, treat your hair gently. Many people wouldn't think of putting their favorite silk blouse under the same stresses they place their hair, and even normal, healthy hair is more fragile than silk. When the hair is permed, you have to be doubly kind to it.
