Micro-Derma Hair-loss Treatment

Clinical studies show that microneedling once every 1-3 a week helps to regrow hair,Then again 1-3 week intervals are the sole frequencies studied for pattern hair loss.

What is Microneedling and how does it work?

Microneedling is a devices with tiny needles that are pressed onto the skin. These needles create “micro-injuries”. And, when repeated often, these micro-injuries accomplish some things:

  • A reorganisation of collagen. connective tissue (fibrosis) is disorganised collagen deposits underneath the skin. By creating these micro-injuries, microneedling devices help to destroy disorganised collagen and lay down new, more organised collagen. (1) And, no, microneedling doesn’t actually penetrate deep enough to make new connective tissue (so long as you’re using the correct needle length).
  • An increase in protein provision. Microneedling stimulates the assembly of proteins like platelet-derived protein and fibroblast growth factor (1), both of which are involved within the regulating the hair growth cycle. (2)
  • Improves topical absorption. By creating micro-tears within the epidermal layer of the skin, topicals can more easily penetrate to the dermal and subcutaneous layers (where the follicle bulge rests). Theoretically, this could afford these topicals to own a greater effect.
  • Encouragingly, these theories and purported mechanisms do translate to hair regrowth in those with pattern hair loss, or androgenic alopecia (AGA) – a minimum of within the clinical studies published to date.

Stage 1: Inflammation of the scalp area

​When it involves needle lengths to avoid scarring, Dunkin et al. (5) found that skin cuts to depths of 0.5–0.6 mm may show signs of inflammation for 24-48 hours following the injury; however, these wounds will close with none trace of connective tissue.

 longer needle lengths – 1.5mm to 2.00mm – also shouldn’t cause scarring… only if the needles are medical grade and used less frequently (i.e., once every 1-2 weeks).

This is why many of us feel comfortable employing a 0.5mm needling device on a daily basis, and why most clinical trials on microneedling have used 1.5mm to 2.0mm with less frequencies (every 1-2 weeks).

 

Stage 2: Proliferation and Healing of Wound

After the initial inflammatory response, the subsequent stage of wound-healing is proliferation. this can be when the wound is rebuilt with new tissues – extracellular matrix, collagen, etc. – that then build the inspiration for brand new blood vessles (i.e., angiogenesis).

The proliferation phase starts immediately after microneedling and should reach its peak after 2 months. nowadays it’s not known how epidermal and dermal stem cells are laid low with microneedling.

 

Stage 3: Remodelling and Maturation

​New type III collagen fibers integrate into the present skin matrix with none trace of fibrotic tissue. a motivating fact is that the new collagen formation is deposited from a depth of 0.6 mm upwards and towards the basal membrane, in most cases when needles with a length of 1.5 mm are used. (8)

Wounds heal within 4-6 weeks. But, the wounding initiated by microneedling may be a (for the foremost part) controlled micro-injury. As such, these wounds take significantly less time to heal.

That said, it’s hard to specify a general healing window for a given microneedling session. this can be because there are many factors which will play into the degree of microwounding and, thereby, the mandatory window for a full recovery.

These factors are centered round the depth of penetration of the needle and individual variances in healing time. Essentially, the deeper the needle and therefore the more pressure used during a microneedling session, the more healing time required – all of which is further influenced by how long your body will fancy heal the treated area.
