Hair Life Cycle
The head of an average adult contains about 100,000 to 150,000 hairs. Hair loss is a natural phenomenon, and a person loses up to 100 hairs per day. At any given point of time, about 90 percent of the hair on the scalp is growing. Each hair follicle has its own lifecycle that is impacted due to heredity, disease, aging, and other factors. The three main phases of this lifecycle are as follows:
- Anagen: This is the active stage of hair growth that may last for around two to six years.
- Catagen: This is the transitional stage of hair growth that may last for about two to three weeks.
- Telogen: This is the resting stage that will last for about two to three months.
Once the Telogen phase ends, the hair is shed and becomes replaced by a new hair, and the growth cycle restarts. Aging, genetics, and other factors may cause the slowdown in the rate of hair growth.
Microneedling to Treat Hair Loss
While it is not a new hair loss treatment, it is often overlooked in favor of more invasive techniques. The use of microneedling works in a similar way to skin rejuvenation, in that it stimulates a wound healing response in the skin. In this case, on the scalp, it can trigger human growth hormone in a targeted way, increasing the blood flow and the scalp’s own oils and healing micro nutrients to encourage hair growth.
Microneedling is a non-invasive and natural way to recover from hair loss or thicken the hair in parts of your scalp. You can read more about the science behind this hair loss treatment here.
Hair Loss Causes
Causes of hair loss may vary from one individual to another. Some of the common factors that may trigger hair loss in men and women include hormonal imbalances, genetic profile, stress, illness, childbirth, certain medications, autoimmune disease, unbalanced diet, and burns or injuries.
According to recent estimates, over 50 million men and 30 million women in the US are affected by the condition of hair loss. A number of surgical as well as non-surgical treatments have emerged over the years to address the problems of hair loss and hair thinning. One of the latest cutting edge treatments that has attracted widespread attention of researchers and scientists focusing on hair regrowth solutions is micro needling therapy.
Types of Hair Loss
- Involutional Alopecia: This is a natural condition where hair thinning occurs with age. Hair follicles increasingly go into the resting stage, and the number of remaining hairs continues to reduce.
- Androgenetic Alopecia: This genetic condition may affect both men and women, and is also known as male and female pattern baldness. Men experience a receding hairline and gradual loss of hair from the frontal scalp and crown. Women experience a general thinning of hair across the scalp.
- Alopecia Areata: This condition usually causes patchy loss of hair in children and young adults. In some cases, the condition may result in total baldness.
- Alopecia Universalis: This condition may cause loss of all hair, including body hair.
- Telogen Effluvium: Changes in the hair growth cycle may cause temporary hair thinning and this temporary hair thinning over the scalp occurs because of changes in the growth cycle of hair. A large number of hairs enter the resting phase at the same time, causing hair shedding and subsequent thinning.
