I would suggest that you need at least 6 weeks before you know what it's gonna look like. Ideally, How Long does it take to Grow a Beardyou should not mess with it as a minimum for that amount of time. If you can let it grow for a few months, you'll know what you have.

Minoxidil is a medicine used to regrow hair and to treat loss of hair. This product is marketed under different trade names such as Amexidil, Avogain, Mintop, Rogaine, etc. Minoxidil can be sprayed, frozen on the scalp or taken orally for hair regrowth without a prescription. 

What is Minoxidil

Minoxidil is a potassium channel opener that causes cell membrane hyperpolarisation. Minoxidil is believed to enlarge the blood vessels and open the potassium channels to reach the hair follicles with more oxygen, blood and nutrients. This can lead to the shedding of the hair follicles in their telogen phase, which in a new anagen phase are then replaced by thicker hair. 

Minoxidil is found to be effective in treating hair loss and regrowth of the hair. The FDA has actually approved the medicine to treat baldness in men. Minoxidil under the trade name " Rogaine " is considered beneficial for male patients with baldness because the hair grows moderately to densely on the head crown. Although it doesn't work for everyone, it was found in a study that approximately 39 percent of men with baldness found it effective for their hair to grow. 

How Minoxidil Works

Minoxidil works by widening the diameter of the hair follicle, causing thicker hair and by prolonging the an ageing phase of hair growth, leading to longer and higher strands of hair. It slows the replication process essentially. According to " Fitzpatrick's Dermatology in General Medicine, " studies show that " up to 60% of men show improvement in vertex balding... with a mean hair density increase of 10% to 12%. "
