to stop hair from thinning you need to improve your health and hair health overall. eat healthy with plenty of fruits and veggies. your hair is mainly made of protein so add more protein to your diet. also some vitamins to take would be b vitamins (e.g.b12), vitamin c, vitamin e, and biotin. also more fish or fish oil to your diet is good and exercise will increase blood flow which helps prevent thinning. if you think your shampoo or conditioner could be causing thinning, try switching it out for a few weeks and see if that helps.
