Accessory Structures of the Skin: Hair Growth and Types

Accessory Structures of the Skin: Hair Growth and Types

Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Accessory Structures of the Skin: Hair and Hair Follicles

Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Summary

Microneedling therapy shows promise for androgenetic alopecia (AGA). It significantly increased hair count compared to minoxidil alone, and combination therapy further enhanced results. Further research is needed for monotherapy efficacy.

Area of Science:

Dermatology
Regenerative Medicine

Background:

Microneedling, a minimally invasive technique using fine needles, is a novel therapy for dermatological conditions.
It is increasingly explored for treating androgenetic alopecia (AGA).

Purpose of the Study:

To synthesize existing literature on microneedling in dermatology.
To evaluate the efficacy of microneedling for AGA using quantitative analysis of clinical trials.

Main Methods:

Comprehensive literature review of microneedling studies.
Linear multivariable regression analysis for evidence synthesis.
Quality assessment of studies included in quantitative analysis.

Main Results:

Microneedling monotherapy significantly increased hair count more than topical minoxidil 5%.
Combination therapy with microneedling and topical minoxidil 5% yielded greater hair count increase than microneedling alone.
Longer treatment duration and reduced session frequency may enhance hair count increase.

Conclusions:

Microneedling shows promising preliminary results for AGA treatment.
Limited studies exist on microneedling as monotherapy; most trials combine it with minoxidil or PRP.
Larger, randomized controlled trials are necessary to establish microneedling's safety, efficacy, and role in AGA treatment.
