Involutional alopecia. This one is less of a medical condition (it's not caused by a disease or genetics) and is more concerned with the hair growth cycle. Also called telogen effluvium, this condition is marked by a long dormant phase of telogen than growth or anagen. This type of hair loss is the second most common next to pattern baldness but is also the most unpredictable and difficult to pinpoint its cause. Studies have shown that the dormancy phase in the hair growth cycle is related to a range of factors, including hormonal imbalances, pregnancy in women, stress, diet, etc.
Another method is to wear a hat or a hairpiece—a wig or toupee. The wig is a layer of artificial or natural hair made to resemble a typical hair style. In most cases the hair is artificial. Wigs vary widely in quality and cost. In the United States, the best wigs—those that look like real hair—cost up to tens of thousands of dollars. Organizations also collect individuals' donations of their own natural hair to be made into wigs for young cancer patients who have lost their hair due to chemotherapy or other cancer treatment in addition to any type of hair loss.
3. Hair fibers. The best (and easiest) way to hide a widening part or sparse patch is with hair fibers. They’re tiny, charged fibers that adhere to your scalp (until your next shampoo). Toppik Hair Building Fibers ($25) come in a range of colors so you can easily find one that matches your own hair. (In a pinch, you can also brush a powdered eye shadow that matches your hair color along your part.)
Testosterone replacement is becoming popular for men. Cotsarelis warns that this may accelerate hair loss. Propecia might help -- but because it prevents testosterone breakdown, it might affect the dose of male hormone replacement therapy. Cotsarelis warns men taking both Propecia and testosterone replacement to make sure their doctor carefully monitors their testosterone levels.
Like a Ferrari production plant where luxury automobiles are painstakingly assembled from carefully crafted parts, hair growth depends on a number of carefully coordinated systems that work together.

Can hair growth supplements have a similar effect on hair loss (androgenetic alopecia) to promote healthy hair growth naturally? Absolutely. In order to understand why, first it’s important to know how your hair grows.
