How Microneedling Works for Hair Loss?

Everyone desires to have thick and healthy hair. It is something you can be proud of. Once you experience significant hair loss, it can affect the way you feel about yourself. It can also limit your style options. Of the few genuinely effective treatments for hair loss, microneedling is one of them. So, how does microneedling for hair loss work and what should you expect during the treatment? Find out in this guide.

What is Microneedling & How Does It Work?

Microneedling is a dermatological procedure involving skin piercing using tiny needles. The process causes the stimulation of collagen and elastin production, leading to new cell production. If performed on the scalp, this can result in new hair growth.

The process of hair restoration microneedling has been proven for its effectiveness, especially in cases of androgenic alopecia and alopecia areata. It works by stimulating the hair follicles and causing the activation of stem cells. When there is an increased concentration of stem cells in the follicle, it boosts the potential growth of additional hair.

Microneedling can be used as a standalone treatment or along with other hair loss treatment products. When the scalp is microneedled before the application of other products, it can cause a significant increase in their absorption rates.

When microneedling is used in conjunction with other techniques, it can trigger the hair follicles to start their growth phase; speeding up the process of hair regrowth. It can help with both hair loss and the thinning of hair.

About the Process

A microneedler or derma roller for hair regrowth is used for the process. It features tiny needles that are rolled or pressed on the skin during the process. The needles cause micro-injuries and cause the following developments:

i. Collagen Reorganization

Fibrosis involves the disorganized deposition of collagen under the skin. Microneedling causes micro-injuries that break the fibrosis and lead to the creation of new and organized collagen.

ii. Boosting Protein Provision

Microneedling causes the stimulation of platelet-based protein and fibroblast growth factor. Both these proteins are involved in the regulation of the hair growth cycle.

iii. Improving Absorption of Topical Applications

Microneedling helps create micro-tears in the epidermal layer of the skin. This allows topical hair loss treatment products to readily penetrate the dermal and subcutaneous layers. This helps significantly boost the effectiveness of the topicals.

Microneedling can be done by a professional, or with an at-home device. When done at home, a cosmetic tool called a derma roller is needed. Needle length of 0.25mm or 0.5mm is considered safe for home use. Longer needle length can be found, but 1mm or more is recommended for use with a professional.

What Can You Expect During a Professional Microneedling Session?

Your hair restoration microneedling session can last anywhere from 45 to 60 minutes.

  • Your dermatologist will cleanse the area on your scalp where there is a need to stimulate hair growth.
  • A topical serum is then applied to the area to numb it. This helps prevent any discomfort or pain.
  • An electric skin needling pen is used to puncture the skin in the targeted area.

It can take 3 to 6 months before you start noticing the growth of new hair in the area.

Microneedling for hair loss is a minimally invasive procedure and you may require multiple treatment sessions. If you have thinning hair, you may require at least 4 treatments. If you have significant hair loss, you may need 6 to 12 sessions to get optimal results.
