HAIR TROUBLE PLEASE HELP :)?

theres no way your hair is going to grow or get healthier without trimming it your hair will just split all the way up to the root and your hair will be worse. you can do a conditioning treatment instead of an oil treatment( shampoo the hair as normal, apply the conditioner all the way through the hair, put on a plastic cap and put the hairdryer on it for about 10 minutes. the heat helps open the cuticle so the conditioner can through.then wash it off. i would suggest getting a trim even if only 1cm cut off
