Last week was the first time I went to my stylist (of 6 years) had no critique for me regarding the condition of my hair, usually Ihe comments that it is on the dry side, but he said it was well moisturized and he had nothing to say but keep doing what I'm doing.
What is crazy is that I actually have a regimine now where I doso much LESS that I ever did and my hair is in the best shape of its life.
I don't cowash and switched to using gentle cleansers, currently Obia Naturals Shampoo bar (previously using KC Come Clean which some people do claim is drying, but I don't find that it is...it doesn't leave your hair coated with moisturizers like some "moisturizing" shampoos, and cleanses really well, I don't know if that's confused with drying, but I don't find it harsh/drying). I do oil treatment overnight before wash day with an ayurvedic oil blend, that is my "deep" conditioner. I don't deep condition or use a rinse out conditioner after cleansing either, I follow up with Kinky Curly Knot Today to detangle (leaving most of it in) and that's it. I've limited washing to once a week on the weekend when I have the most free time. Styling I use Obia products, the moisture cream and curl enhancing custard, they are made with non drying ingredients and have conditioning properties. I mist daily during the week with the Obia moisture mist (water based spray with oils) and that gives me my daily moisture shot. Every other day or so I may add a dab of coconut oil when I shake and fluff my hair in the morning and go.
I've come to the conclusion that it really is all about the products we use. We can deep condition till we pass out but if there is something in there, or in another product we are using that is drying, or blocking moisture from penetrating the hair we have these dry hair issues. I'm using less product that contain less ingredients, gentle cleansers, spending less time on my hair, and my hair is more moisturized than it was when I was intentionally trying to load it with moisturizers. This all transpired for me over the past 3 months. I thought my hair was healthy before, but there is definitely a difference and improvement in the condition of my hair today that everyone has been noticing.
Take a look at the products you are using and see if there are some changes you can make on that end. Also, remember, your ends are the oldest part of your hair, so they will be naturally more dry and the driest part of your hair. If you haven't had a trim in a while, you may find you have dry ends, knots and lots of tangles. You may want to consider trimming some of that older hair off the ends if this is the case (I know, I know... folks here don't like that suggestion lol), that will help out with the tangling (trust me).. Then keep that focus on maintaining moisture balance with that new trim giving you a semi fresh start.
HTH, I'm sure other's will pop in provide some great insight if you don't find that any of this was helpful.
Good luck!
