They are gel, serum, and foam forms. It is mainly used to treat hair baldness and the healthy growth of hair. It helps to strengthen the growing process of hair and lengthens the strands of hair.

The effectiveness and results of minoxidil medication may be different for every individual. The changes are usually visible after continuous use from three to six months.

The hair growth process starts to begin after that period and may only keep going if the medication is still in use. Hair loss might begin again once the medication has been stopped for a few months.
