Most men are affected by the same problem at some point in their lives… hair loss. Whether it’s male pattern baldness, a form of alopecia, hair thinning, a receding hairline, etc. there’s no need to panic! We’ve got the best hair vitamins and supplements to the market today! 

What is DHT? How Does it Affect Male Hair Loss?

DHT stands for dihydrotestosterone, a male sex hormone that attach to receptors in the scalp and lead to hair loss. If you’re genetically prone to male pattern baldness, DHT can cause the hair follicles to shrink and in some cases stop new hair growth altogether.

To get a better understanding let’s look at the four stages of hair growth:

  1. Anagen Phase:  The cells in the bulb divide and produce new hair. A single follicle is active between 2-7 years and in that time can grow as much as 30 inches of hair. After that time, the follicle will become dormant. 
  2. Catagen Phase: Compared to the anagen phase, this phase is short, often only a few weeks. During this phase, the hair stops growing and detaches from the blood supply. The hair at this stage is referred to as club hair and 3% of hair is in this phase at any given time.
  3. Telogen Phase: New hair begins to grow underneath the club hair. This phase lasts for about three months. At the end of this phase, the club hair will fall out to allow the new hair to grow. The average person loses 50-100 hairs a day to this process (which is completely normal).
  4. Exogen Phase: Referred to as the shedding phase. The average person loses 50-100 hairs a day to this process (which is completely normal). Allowing new hair follicles to grow in as the old ones fall out. 

Saw Palmetto…Say What?

Wondering what Saw Palmetto is and what it has to do with male hair loss? Saw Palmetto (Serenoa repens) is a supplement produced from the fruit of the Serenoa repens tree. It produces fatty acids and sterols which can stop the creation of 5 alpha reductase which can build-up around the base of the hair follicle. This enzyme converts testosterone into the kryptonite hormone called DHT. By slowing down 5-alpha reductase, Saw Palmetto helps reduce the DHT levels as men age.

Saw Palmetto also helps loosen build up on the scalp that restricts micro-circulation and capillary blood flow and delivery of vital nutrients and minerals to the follicle papilla and cuticle. Beta sitosterol in Saw Palmetto can help prolong and initiate normal hair growth stages by stimulating restricted enzyme accumulation in both men and women.

According to a study found on the National Library of Medicine, 50 male volunteers ages 20-50 years old received topical Saw Palmetto products for 24 weeks. Their hair count grew at weeks 12 and 24 compared to the baseline.
