Dear Shari: Why is my hair greasy??? I take showers every day and I get grease if I go under the front part of my hair (if that makes any sense). I don't know why—I use sulfate-free shampoo and Suave Naturals coconut conditioner.

A: Without knowing the history of your hair and your diet, it is difficult to offer a solid answer. However, there may be synthetic ingredients in the products you are using that are weighing down your hair and causing a reaction. Is your facial skin oily as well? With limited information, I would like to suggest that you only use the conditioner on your ends and not on your scalp. Also, when you are cleansing the scalp area, make sure you scrub well and rinse well. Lastly, if you are using any stylers on your hair when it is dry, this, too, may be causing the greasy effect.

DevaCurl No Poo

Dear Shari: I have 3b (50:50 chemically treated, natural-in-the-process-of-growing-out) curls, and I've been using Deva No Poo for almost close to a year now. I have found myself on an extended vacation in Grenada (Caribbean), and it's probably the weather and frequent ocean swims that have lead me to wash my hair more often than usual (from twice a week to three times a week). And I've run out!!! Any suggestions? I have at least another 3 weeks with no access to any line of sulfate free shampoo....what do I do? My scalp is drying me crazy. Also what's the deal with sea water...good or bad?

A: Sea water contains salt—BAD for the hair. It is dehydrating. I suggest that you use conditioner as both the cleanser and the conditioner and leave some in when rinsing for extra moisture. Make sure the conditioner does not contain silicone as it will clog the hair and prevent moisture from penetrating.

Dear Shari: I've been shampoo free for about 2 weeks now, and my hair is already feeling great, but I'm having a situation with my root hair. It's super oily/over-conditioned, I don't know, it's impossibly soft. Perhaps it's only the change, going from a sulfate shampoo to co-washing... So I thought I'd better use a low sulfate shampoo every two weeks or so. I don't know what to do.

A: There is nothing wrong with only using DevaCurl Low-Poo which has less moisture than DevaCurl No-Poo. In addition, do not use the conditioner on your scalp at this time. It seems not to need it.
