I have been experiencing hairfall for more than a year now. But hair growth has also been good so thr hairfall was not causing any disturbance to me. But last 4-5 mo ths I can see my hair thinning and hair fall has increased tremendously. I take biotin 10000mcg 1 tablet a day and multi vitamin too. My diet hasn't changed much too. Could you please tell me what could this be and how do I treat it ? Thank you so much in advance.
