I moved to paris from india 4 weeks ago, and i think after 1-2 hair washes after coming here is when i started noticing that a lot of my hair is falling out. when i pull my hair with the slightest force, a lot of fail falls out and if my hair is wet, it falls out even more. and I dont know if im not shampooing properly or its some kind of issue where even after washing my hair, the back on my head still remains greasy from the roots. the recent major changes in my life would be environmental change obviously and I think it might be diet as, as students we dont really have time to cook proper meals while managing studies, but i’ve had poor diets before coming here too and my hair was okay that time. and another change is that paris is really cold for me, ive never stayed in cold weather like this. I was facing hairfall even before this but it wasn’t so prominent but i used to think that was because i used to bowl dry my hair and straighten it lightly after showering for almost 6-9 months. but I haven’t used any styling products (dryer and straightener) after coming to paris expect in the first week i came here, i used it once. so i want toknow the cause of my hair fall and how can i prevent it and regrow the hair that is lost ?
