How Microneedling Works for Hair Loss?

Everyone desires to have thick and healthy hair. 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 and 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 micro-needling has been proven to be effective, 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.


The benefit of microneedling for the hair growth phase 

Microneedling can be used as a standalone treatment or with other hair loss treatment products. When the scalp is micro-needled before the application of other products, it can cause a significant increase in its absorption.

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 microneedling process

A micro-needler or derma roller for hair regrowth is used for the process. It features tiny needles 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 fibrosis and lead to the creation of new and organized collagen. Collagen is the glue that holds our cells together and is vital for hair growth.

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 penetrate the dermal and subcutaneous layers readily. 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. A needle length of 0.25mm or 0.5mm is considered safe for home use. Longer needle lengths can be found, but 1mm or more is recommended for use by a professional. In this blog we will discuss:

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.


How to use a Dermaroller for hair regrowth at home

What is a Dermaroller?

Derma Rolling is also known as microneedling. Dermarollers are cosmetic tools made of many high-grade micro needles which roll over and penetrate the skin's upper surface painlessly.

Outfitted with 540 tiny needles, each Dermaroller provides your scalp with vital micro-dermabrasion to open up the pores, providing two major benefits.

  • They stimulate collagen growth which significantly improves the appearance of scars, fine lines, wrinkles, stretch marks, and acne scars if used on the face.
  • They allow the transdermal application of creams, gels and oils, to be absorbed far more effectively - boosting their effectiveness. This is relevant to topical hair loss treatments, allowing the saturation of the follicles.


 How does the Dermaroller benefit the scalp?

 As you roll over your skin, it creates pinpoint punctures into the dermis – the majority simply pushing your pores open temporarily.

This is perceived by the body as damage, which stimulates the release of growth factors that trigger the production of collagen and elastin.

The human body naturally reacts to any injury by initiating the healing process, but it will only heal as far as it must to keep you healthy – which is different from healing on a cosmetic level. By persistently triggering the healing process, you encourage your body to continue healing until you are satisfied with the results. 

By opening the skin in this way, you dramatically increase the penetration of any topical product, increasing its efficacy. Also, miniature perforations that stimulate the skin’s healing mechanisms are created, increasing the production of many important factors for healthy skin.

Dermarollers comes in different size needle length. The sizes considered safest for home use are 0.25mm or 0.5mm. There are needle lengths of 1mm or more, but these are recommended for use by professionals. 

Studies show that for the absorption of topicals, 0.25mm is effective. For more 'wounding' of the scalp to create more of a 'healing' effect, 0.5mm length is effective. Therefore, for those who want to increase the release of growth factors that trigger the production of collagen and elastin, using 0.5mm will be effective.
