Hello Doctor, I've facing hair thinning and slightly hair loss from last few months! Few months before I tried shaving my head 2tyms per month though it increases hair thickness but actually it made my hair look worse than it is before I mean it feels my hair got thinned in front and sidewards. The reason I think is not only trimming but also my late night sleep and food habits. Adjusting sleep and food habits may fix my hair but it's too late now I feel. Does taking vitamin supplements helps my hair thicken nd be healthy? If so which ones? Or do I need to consult doctor? And finally Which shampoo is safe to use? Please advise me. Thank you.
