Late to the party but:
Through 7 years' trial and error with my natural, mixed race hair (very thick with tangling tendencies) I have found that tools, products, and application method all matter.
Tools:
I like the Tangle Teaser but in reality, as my hair gets longer, it tends to create single strand knots at the ends of my hair. I find a very wide toothed comb is less of a problem and easy to use.
If I am wearing a wash and go and need to dry my hair I use a diffuser. I use it on medium heat and position it before turning it on and turn it off before re-positioning it. That way I don't disturb the curls too much and there is less frizziness.
Application Method
I detangle with my rinse out conditioner or treatment in the shower, rinse out then use a cloth towel rather than a fluffy one to pat my hair so it's wet and dripping a bit but doesn't frizz up. I section it out into between 4 and 6 bunches using bulldog clips, tucking the ends under to stop them drying and frizzing out then apply products in a smoothing motion moving from roots to ends in sections a few of inches wide and not too chunky/thick.
Products:
I use the curly girl method more or less. Co-washing with conditioners that have silicone (like Aussie Moist, Herbal Essences and Organix Coconut) does not work for me, even though they're quite nice conditioners. Major itchy scalp and build up. I occasionally co-wash with a silicone free conditioner like Tresemme but it doesn't have enough slip for me and I still get itchy within a day or two. I prefer a silicone free shampoo (Keracare naturals or Giovanni) or cleansing cream like the As I Am coconut co-wash or the one by Keracare naturals.
Heavy leave in products with or without silicone (some of which are marketed as suitable for afro hair) don't work for me - certainly not as my main product. I need moisture from a water based conditioner with some slip and an oil and a bit of cream to seal it in. I tend to use the following:
Giovanni Direct leave in is great. It is silicone free and a medium/light moisturising leave in conditioner. It's not enough by itself, but if I use the LOC method (layer in this order: lotion, oil - jojoba or almond or olive then cream) I get soft defined hair that lasts some days with care. I am currently using Bee Mine cream for the last step but it's no longer available here in the UK. Try something from the "Curls" brand (from many Afro-Caribbean shops or from British Curlies website) or the Camille Rose Naturals brand (available from Zara Beauty on the Walworth Rd, London or online) you can use any rich moisturising cream for this.
I do occasionally use gel if I want lots of definition but only the Kinky Kurly one or the Eco Styler gel with olive oil (none of their others- too drying).
I still go back to the Kimmaytube leave in recipe as my hair likes that. Google it but it's Kinky Kurly Knot Today, plus Aloe Vera juice, plus a bit of light oil like almond plus a bit of castor oil. Works a treat.
Overnight I sleep on a satin pillowcase and when hair is short I wrap the front to stop my hairline getting too frizzy or when long I use the pineapple method (high loose pony tail).
Despite all this I am chronically lazy and don't have lots of time for my hair as a working mother. It's slightly longer at the moment and I cane row it and leave it for a few days, wearing a satin scarf at night; or else a high puff. I have been meaning to try two or three strand twists but can't be arsed to spend the time at the moment.
I cut it very short every few years and actually love it like that as you get a few "Halle Berry" comments (more like Eartha Kitt on a bad day when I'm stressed and tired
) and it's a real sense of freedom to have a short, chic look (a bugger if you colour it or want it looking just so all the time as you have to get it cut every 4-6 weeks). Like others I struggle to find good hair dressers who can cut my hair well, whether they are European or afro. Michael Price at Unruly (London) is good. 3Thirty in Old Street, London are also good. I have decided to give Matthew James a try. I have found that when I wear my hair short I get the best cuts (and I mean really good) from afro barbers: yes the traditional ones who finish you off with clippers or a wet razor! I have been in to the barber who cut my DSS hair with random pictures from the internet and he has done a really good version each time.
Didn't mean that to turn into a bit of a ramble!
