Hello. Taking cetrizine once in a week is ok. I dnt think there is any correlation betn cetrizine consumption n hairfall.
Hairloss of 100 strands per day is normal so dnt wry if your loosing 5-10 hairs per day. Use medicated shampoo like triclenz or hair 4 you on regular basis. Do not oil your hair during day time, oil d hair 10-15 min before hairwash. Juene hair oil 2-3 times per week.
Include protein rich food, green leafy vegetables, fresh fruits n juices in your diet, drink 2-3 lit of water, daily exercise of 45 min is must. You can use altris hd hair colour to colour your hair, its mild herbal product.
Thanx.
