Male Baldness Info

what is rogaine and what does it do to your scalp does it generates hair growth in parts of the baldness. is it suitable for my boyfriend with male pattern baldness.

so im trying grow my hair back out and whenever i do this my hair looks like crap forever before it finally gets to a certain length…so for the first time in about 2-3 mnths i tried spiking it up and noticed that when i did that you can see my scalp..why is this?…my hair is still actually pretty thick…im only 20-21..granted male baldness does run in my family but how can my hair be thick still and my scalp be showing?…any suggestions on what i can use to prevent my scalp from showing…also i only use mousse(no gel) but i dont brush my hair, i usually just let it dry..i shampoo and condition 3-4 times a week…
