What Makes Your Skin Dark To understand whether you can increase hair density, it is important to first understand how hair grows. Each hair strand grows from a follicle located in the scalp. These follicles go through a natural cycle consisting of growth (anagen), rest (telogen), and shedding (catagen). At any given time, most healthy follicles are in the growth phase. Hair density decreases when follicles shrink, become inactive, or produce thinner hair strands over time. This process is known as miniaturization and is commonly seen in pattern hair loss. Whether hair density can be increased depends largely on whether the follicles are still alive and capable of producing hair. http://sknlex.com
