Well i used to straighten my hair every single day, thinking it wouldnt catch up to me because i used heat protectant, but was i way wrong. My hair looked like a broom stick. So what i did to save it was cut 3 inches off, and embrace my natural curls. Instead of straightening my hair, i just put some mousse in and let it all go. I also take multi vitamins like biotin and one a day. I went from shoulder length to mid back in 5 months! Hope this helped!
Get a good conditioner and make sure you use a heat protector every time you use a blow dryer and any other heated styling tools. Also when dry your hair only run the towel from roots to ends and do not rub back and forth. Your hair is made of scales and rubbing back and forth raises the scales causing the split ends.
I know you are holding on to past follicles gone by, but for your own good PLEASE start accepting the fact that they are dead, all of them. Just give yourself enough time to start growing anew again. Chia pets are willing to donate/model an example of how you can go "Green" without any "stops" and move forward.
U can add oil to your hair! Or put Vaseline on ur ends. Or u can stop using heat products on ur hair, I did this and my hair grew and inch in one week and my does NOT grow fast, this also helped my hair repair from heat damage and cancel split ends!
You can't repair split ends. You need to cut more off of your hair to get all of the split ends off or it will just keep breaking and splitting more. Then do deep conditioning treatments once a week and try not to style your hair with heat It will grow out quicker, since it's not breaking off and you wont need to get it trimmed as often,
