I had the same trouble with my thick 4b hair. I got sick of putting heat on my hair for unwearable results so I started looking up straightening natural hair on youtube and found soooo many uploads! The only issue is people have alot of different methods so you should search for the best method for your specific needs. I found some things that help most were
1: Using "the chase method" it requires a small tooth comb. Check it out on YT
2: Getting my hair properly blowdried (in easily managable sections) Using my Yellow Bird blowdryer with blowdry comb attatchment (there are better dryers out there but this works for me! $40 at Sallys) make sure you get roots. Be gentle!!
3: always ALWAYS using a heat protectant before blowdrying and after, directly before flat ironing. I use Chi silk infusion which is pricy but effective. I hear ic fantasia heat protecting serum works well too or silk elements.
4: investing in a good flat iron. I reccomend folica.com they have soooo many to choose from! I love visiting their site
*other tips- i ways detangle in the shower with kinky curly knot today and leave it in. Before drying i put a little reds kitchen sink soc it 2 mii curls all natural jel. I never iron above 350 ib fact, i try to stay as low as i can go most of the time 250 to 300 degrees f. When im finished ironing i use a little bit of emu and jojoba oil to massage into scalp and ends. Not too much! Or you wont have that flo you desire. It just helps nourish
I hope this helps!!
