My hairs are falling now a days and corners are growing. They have become dry and dull. Water we use contains more amount of solids in it (approx above 500). I wash my hairs followed by conditioning them on alternative days. I use patanjali shikakai and milk protein mixed shampoo and protein conditioner. I generally use alum mixed water for hair wash. Would you please help me to improve hair strength? Please suggest also how to mix alum with water properly as I don't know.
