Hello, I can understand your concern for hair fall at the age of 27 years. This can be due to stress, dietary imbalance and any long term disease state. As you are female so it is quite obvious to get low hemoglobin and stress issues related to day to day life. I suggest my patients to biotin, calcium pantothenate and other vitamin B complexes. Additionally increase you protein and healthy food intake on daily basis and eat sprouts. Eat a lot of green leafy vegetables and sprouts which contains vitamins and minerals necessary for normal hair function. Applying oil has not impact on hair loss. Minoxidil in lotion form can be used to improve hair growth and is prescribed therapy. Minoxidil do not cause any side effect and you can take further guidance from a dermatologist. all the best.
