I am currently suffering from hair fall. I've tried protein shampoos, scalp solutions and even eating healthier but it does not seem to work.?

Depends on cause... One's primary care doctor can check for medical causes. If none are found, then one can see a dermatologist, especially one specializing in hair restoration (some treatments: minoxidil, etc, ...). Medical causes may include: hormonal problems (low thyroid), seborrhea, alopecia areata, stressful illness. Other causes: genetic male/female pattern baldness, telogen effluvium.
Won't work. If this is telogen effluvium, nothing will help and it will self-cure. If you are hypothyroid, you need to be diagnosed. If it's alopecia areata, nothing works. If there is a fungal scalp infection, a variety of Rx's exist but quacky protein shampoos won't touch it. Eat healthy for its own sake but know it's not the key to managing or preventing most illness. Best wishes.
