Almost all men experience some sort of hair loss or hair thinning at some point in their lives. External and Internal factors such as genetics,hormones, and age all play a vital role in when/where hair loss occurs and also how extensive the loss/thinning will be. Miniaturization better know as Hair thinning is usually the primary stage of hairloss. The rate of Hair growth mainly depends on a proper functioning hair follicle. For most men and women, the hair follicles moves through a constant cycle or growth “anagen phase” or rest “telogen phase.” When hair thinning starts, the length of your telogen phase increases. Since the resting/telogen phase is longer, the shafts of new hair become much more narrower. As we get older, the telogen phase gets longer and longer, resulting in progressively thinner hair until eventually our follicles stop functioning completely causing follicle death where hair will no longer grow.
DHT Hormone Dihydrotesterone and Male Pattern Baldness
Research has shown that the male hormone DHT “dihydrotestosterone” is what is primarily responsible for most hair loss due to its interaction with the cells of our hair follicles. DHT’s interaction with follicles cause an increase of the telogen phase in normal hair-growth cycles, which leads to hair thinning and the eventual death of future hair growth. Its interesting to note that not all follicle cells are susceptible to DHT hormones. DHT’s effects are fairly predictable to a trained doctor which is why its referred to as “pattern baldness.” Other names for Pattern Conditions include:
- Male pattern alopecia
- Pattern baldness
- Androgenetic alopecia
- Alopecia androgenetica
Areas that are the most susceptible to the effects of DHT are usually located in the front of our scalp directly above the temple region. Gradually, over time, our hair follicles in the back of our heads (crown areas) also begin to show the effects of hairloss till the 2 areas meet near the middle resulting in total hairloss of the scalp.

Usually the hair follicles on the side of our heads are not as susceptible to the degenerative effects of the DHT hormone but can show signs of thinning. in 1975, Dr Dr. O’tar Norwood developed the internationally used “Norwood Classification system” as way to identify the 7 stages of hair loss.
