How to care for medicine-treated hair?

• Dilute shampoo with water before applying to scalp.
• Apply conditioner to hair excluding scalp to prevent the latter from becoming too oily.
• Hair shine products should only be applied to hair, not on scalp.
• Change hairstyle (or the space you leave in between your hair when combing) once in a while. 
• Have your hair trimmed every two months to minimize hair fall.
• Buy hair and scalp treatment or hair spa from a reputable store and use it twice a month to replace lost nutrients. This may be done at home instead of paying for a pricey salon service.
• A more natural way is to take calcium for good hair growth and to prevent hair loss.
• Comb hair from bottom to top. This way, tangles are avoided.
• Wide-toothed comb like paddle brush is advised especially for long hair.
