I am a type 2c curly girl and I've been NC for a while now but just recently started researching NC hair care. I have thin to med. hair thickness and my hair is slightly course.
Here are some things that have been successful for me;
Try going no or little shampoo. I've been going four days or so between shampoos and co washing( washing with just conditioner) on the non shampoo days. I thought I would hate the co wash method because my hair is sometimes oily. However, when I tried it my hair was just as clean as w/ shampoo. It was also shiner, softer, curlier and less frizzy.( needless to say, I was pleasantly surprised).
Try using an Apple Cider Vinegar rinse 1 or two times a week. This will cleanse your scalp of any dead skin cells, bacteria and product residue. It also restores the ph balance of your hair and scalp and helps with split ends. I noticed that my hair is healthier over all when I do this.
I mix 1 tbsp. ACV with 1 cup warm water and poor into my hair after conditioning, concentrating on the ends and scalp.
If you don't like the smell, you can brew 1 tbsp. of herbs that are good for hair health (i like lavender) in 1 cup of water and add the ACV. That helps some.
As for hair cuts, I'd go with long layers. I've found that short layer on myself tend to poof out and look weird. Especially since my bottom layer is not very curly.
I've tried a lot of products but my top three fave are Herbal Essence Tousle Me Softly Cream.( I like the gel too, but if I could l only get one it'd be the cream). It has a good hold and is good for "reviving" your curls the next day. It also last a long time.
My second fave would be the Garnier Fructis Anit- frizz Curl Calm Down. It doesn't really have enough staying power to style my hair when i use a defusier, but it is good for fighting frizz and "clumping" curls. I use it after I style my hair mostly on the ends to protect ageist friction, it works pretty good for that and for a wash and go.
I just got some FX Special Effects Curls Up staler and I do love it..It holds good and fights frizz the best out of the three I've mentioned. It doesn't make your hair crunchy and has the added benefits of Chamomile and vitamin E so it's says it helps with split ends. The only down fall is it makes your hair feel kinda odd. I can't describe it...just kinda heavy. But it's not unbearable and I still love the stuff.
As for special tips I'd say try the NC pineappling method and a satin pillow case or cap when you sleep. Also use only a wide tooth comb as brushing and small tooth comes cause damage and frizz.
Good luck and hope this helps.
