would like some advice *new*

hi, this is my first time on this site and i would like advice on how to achieve healthier hair. I'm not exactly sure how ya'll rate hair on here but i'll describe what mine is like. my hair is a few inches below my shoulders and thin in my opinion. the ends are not the best but the rest of my hair seems mostly healthy. when i was younger (until just recently) i always wore my hair in a tight ponytail and i have lots of breakage. i also have thinning hair in the font from the ponytails i would always wear. my mom has been relaxing my hair for a while but i usually go months on end without using one because it usually burns my scalp and my hair feels soft enough without one. i should also mention that sometimes when i brush or comb my hair it comes out at the roots....im very concerned about this. i wach my hair once a week with shampoo and conditioner, let it air dry, and then straighten it. when i straighten it i use pink hair lotion and then i run over it again with the straightener everyday in the morning. i usually then just pull it back into a ponytail. and sometimes i use the organic root stimulator olive oil sheen spray but only recently. i am planning on going to a salon soon to get my dead ends trimmed and to get a real haircut so that i dont have to wear a ponytail everyday. i am also planning on buying a chi straightener and using a heat protectant regularly. i would like some advise as how to get my hair much thicker and healthier. and also i would like some advice on a good hair care regimen and what products you would recommend to use. also please recommend products that will help my hair grow. thank you.

Is your hair fully relaxed now or are you transitioning? Applying heat every day that might be a problem. Try reducing that. When you see your hair when it comes out is there a white bulb on the end? If so you may be more shedding than breakage. If you don't mind me asking why do you straighten your hair everyday? I know when I was fully relaxed after I washed and flat ironed my hair it would be fresh for days with out needing a touch over.  Do you wrap your hair at night with a silk scarf? That can help preserve the style until your next wash. A good regimen starts with the inside out. For outside, wash (or co-wash), deep condition, and moisturize (not oils are moisturizers).  For inside, take vitamins, drink water, eat more fruits and veggies, and exercise. There products that help with growth, but the key is to look for ingredients that promote growth like rosemary, nettle, and sage to name a few.
