Hi and welcome to LHCF!
I agree with all the other product suggestions mentioned.
One thing, be careful with Surge as a detangler. It has keratin protein in it and can cause brittleness with over usage.
The burns/irriation that you may have heard of are from spraying directly on the scalp. I, myself, experienced some scalp lacerations and irritation. However, with frequent washings this can be deterred. Another deterrant, that has helped other ladies, is mixing it with an oil. I followed my applications of Surge with an application of evoo or Wonder 8 Oil with great results. Remember everyone is different. You experiences may not mirror other's experiences. The best way to find out what works for YOU is to try it yourself.
Also, check your washing technique. The way your manipulate your hair during washing can be a factor in your tangling as well.
I wash my hair in four ponytails. Another good way to wash to avoid tangles is to wash smoothing your hair back in one direction. Or combing through while the water is running over your hair.
Happy hair growing....
