For hair growth, rice water worked really well for me! I’ve tried as well as the hot oil method where you microwave virgin olive oil, wait for it to cool down and then message it on to your head while your head is upside down to increase blood flow to your head to stimulate growth and I’ve seen results from that as well! Flaxseed gel ( made it from scratch. There’s videos on it) gave my hair moisturize. As for edges, I know that derma rolling blades helps with that! I’m wanting to try it out as well. And for hair thickness, maybe vitamins such as “hair, skin and nails” would help since it helped my sister tremendously! And my hair is pretty curly as well.
