Hello, Welcome to healthcaremagic Severe hair loss over few months is acute telogen effluvium. It is a hair loss pattern usually triggered by a physical illness like viral fever, typhoid fever, hepatitis, etc which you would have about 3 - 6 months prior to onset of hair fall. It could also be due to underlying anaemia, thyroid abnormalities, crash dieting and weight loss. You need to check your hemoglobin levels, serum ferritin levels and thyroid status. Please have good diet including green leafy vegetables, eggs, dates, biotin rich foods like carrots, almonds, walnut, cucumber, cauliflower, milk. Please try to increase your weight. Curlzvit has biotin, calcium pantothenate and antioxidants. It will be useful for both hair fall and greying. Continue it for 3 months. Premature Greying is still a poorly understood entity. The causes suggested are genetic, Vitamin deficiencies, Stress etc. The treatment recommended is vitamin supplements with 100 to 200 mg of calcium pantothenate. Even Biotin and anti oxidants help. Altris gel is a new product in the market(Melitane) which has peptide which stimulates the pigment producing cells of hair. Sufficient studies and experience is not yet available for it. But it is definitely not harmful and product is launched for the indication of premature greying. Hope this helped Take care
