Hair loss does not just constitute one of the most frequently experienced issues for dermatologists, it dispenses a significant negative effect on one’s personal satisfaction. Advanced Pattern Hair Loss (PHL), particularly at an early age is often a wellspring of depression in youthful grown-ups. Androgenetic alopecia (AGA) influences the two sexes in a particular example of hair loss from the scalp (MPHL for male PHL and FPHL or female PHL). Bitemporal subsidence influences 98.6% of men and 64.4% of women; while mid-frontal hair loss affects about 66% of women and 75% of men above 80 years old. Loss of hair from the vertex is typical of MPHL, experienced in a larger part of affected men. The sign of the condition is dynamic and continuous scaling down of hair follicles (HFs), joined by dynamic abatement in the span of anagen and decrease of anagen to telogen proportion. Furthermore, in AGA, there is a delay between the end of the telogen stage and the start of the new anagen stage; a resting stage called kerogen during which the hair follicle stays empty. The follicular scaling down in AGA is an offbeat phenomenon even inside a follicular unit (FU); with the affection of auxiliary follicles happening in the underlying stage and the essential follicles in the last. Conversely, the scaling down process is synchronous in alopecia areata (AA). The etiopathogenesis of AGA is mind-boggling. The central point associated with the pathogenesis of AGA is the undesirable androgen metabolism at the hair follicle level. The hoisted action of Type II isoform of the 5-alpha-reductase (5AR) compound, which processes testicular testosterone circulating in the blood into dihydrotestosterone (DHT) in the genetically inclined hair follicles of the temporal and vertex locales, is the most noteworthy factor in MPHL.

Hair follicles of the temporal and vertex zones of the scalp express androgen receptors copiously that bind to the expanded neighborhood levels of DHT, bringing about the shortening of anagen and dynamic scaling down of thick, pigmented terminal hair into thinly, non-pigmented vellus-like hair. Finasteride (FIN), the only United States Federal Drug Administration (FDA) endorsed oral operator for MPHL is a particular inhibitor of 5AR, type II isoform. Minoxidil (MNX), the other FDA endorsed topical operator (for MPHL and in addition FPHL) clearly acts by expanding follicular vascularity (as a potassium channel opener), prolonging anagen and shortening telogen, and also by changing over mostly scaled down (transitional) hair follicles to terminal hair. Hair transplantation obviously stays truly one of the best and in some cases the main therapeutic alternative in cutting-edge AGA.

Basically, there is a four-fold motivation to investigate new treatments for AGA. Firstly, the improvement with MNX as well as FIN is restricted and keeps an eye on level following one to two years of consistent use. The achievement rate of treatment for AGA scarcely surpasses 30% utilizing either of these agents; which brings the second reason to the fore, i.e., a high probability of other pathophysiologic pathways being associated with this condition. For sure, there is currently adequate proof supporting the part of components other than hormones contributing essentially to the pathogenesis of AGA. Thirdly, the sexual adverse effects (SAEs) of FIN, whether sustained actually or due to the nocebo impact, and the monotony of twice-day by day utilization of MNX often lessen patient compliance, requiring the improvement of novel therapies.

Mesotherapy, Microneedling and Platelet‐rich plasma (PRP) are various cosmetic methods being applied for different sorts of alopecia.

To begin with, Mesotherapy is a noninvasive method in which dynamic substances are conveyed just underneath the epidermis by means of shallow smaller scale injections. Different substances including vitamins, prescriptions, plant extricate, and other bioactive mixes including vasodilators, finasteride, and minoxidil can be injected subcutaneously to achieve the objective tissues in Mesotherapy.


In recent years, Mesotherapy is progressively being utilized as a part of the treatment of telogen emanation, androgenetic alopecia, and alopecia areata. Despite the fact that the correct component of how the Mesotherapy functions aren’t known, a few hypotheses have been estimated. According to Pistor, the skin might be a point for incitement which is activated by Mesotherapy that sends inhibitory signs coming to the horizontal medullary center of the spinal cord. These inhibitory signs have been proposed to be either created by the needling itself or the pharmacologic substances given during Mesotherapy. The objective tissue of hair Mesotherapy is, for the most part, the dermis including the circulatory, neuronal, and immune component. Additionally, epidermis and subcutaneous tissues are influenced by the methodology of dissemination of substances. As indicated by Mesodermic hypothesis, Mesotherapy follows up on the tissues got from mesoderm including capillary and venous spaces, neuronal parts, and immune cells of the skin.

The aim of hair Mesotherapy is to restore the strange physiology causing alopecia by fortifying different organic reactions by injecting the dynamic substances into scalp. Furthermore, mechanical incitement by needling itself makes a biologic reaction that is relied upon to animate mesodermal changes. Hair Mesotherapy offers the counteractive action of hair loss, initiation of new hair growth, and the change in the nature of existing hair. By hair Mesotherapy, nearby microcirculation is expanded, which enhances nature of hair follicle for better growth. Also, nutritional supply is given to the hair follicle and the abundance of dihydrotestosterone (DHT) is proposed to be neutralized. Although, there is no institutionalized formulation utilized as a part of hair Mesotherapy and the different ingredients can be given depending upon the sign. Generally, cocktails containing a blend of various ingredients utilized as a part of hair Mesotherapy and they can be applied in rotation depending upon the clinical reaction. Generally used substances in hair Mesotherapy incorporate minoxidil, finasteride, dutasteride, biotin, tretinoin, pantothenic corrosive, pyridoxine, procaine, dexpanthenol, azelaic acid, T3/T4, and different vitamins and minerals. These compounds have distinctive biologic impacts. Particularly, buflomedil, minoxidil, finasteride, dutasteride, biotin, vitamins, and organic silicium are proposed to stimulate new hair growth.

Microneedling is another technique employed for hair growth and restoration. Microneedling is a medical procedure done by a drum‐shaped roller gadget with several micron‐sized microneedles (0.5– 1.5 mm long) projecting on it. Prior to the treatment, local anesthetics must be applied to the zone. Roller device is applied in vertical, horizontal, and diagonal directions. By rolling the device over the skin, these microneedles penetrate the stratum corneum and make various transient small-scale channels over the applied surface without harming the epidermis. Microneedling gives guide passage to suitable epidermis where it follows up on, and does not contact with the dermal nerves and capillaries.

Microneedling drives the incitement of stem cells and initiation of growth factors. It expands the bloodstream to the hair follicles. Also, transient micropores shaped through the methodology permit the conveyance of particles into the epidermis. Subsequently, in the wake of Microneedling, numerous cosmeceutical operators have been recommended to be delivered deep to the skin. In general, Microneedling is connected at 4 to 6-week intervals in order to wait for new collagen synthesis.

The last however not the least is the function of Platelet‐rich plasma in the treatment of alopecia.

Platelet‐rich plasma(PRP) is an autologous, biologically active concentration, made out of numerous growth components, cytokines, and plasma proteins. It came into utilization since 1970s attributable to its belongings to promote the wound healing to a cellular level. Platelet focus in Platelet-rich plasma (PRP) is no less than 1,000,000/μg/L in 5 mL and the growth factor fixation is 3– 5 times higher than peripheral blood.

There are four distinctive PRP subgroups accessible; unadulterated or pure PRP, leukocyte and PRP (L‐PRP), platelet-rich fibrin matrix (PRFM), and leukocytes and platelet‐rich fibrin matrix. Clinically, pure PRP and L‐PRP are widely used. The one widely utilized as a part of cosmetic dermatology is the pure PRP. In vitro studies demonstrate a dose‐dependent positive connection between the platelet concentration and human mesenchymal stem cells and fibroblast multiplication and sort 1 collagen generation. In dermatology and cosmetic medicine, PRP has been used to treat skin inflammation, scarring, and alopecia (particularly in ladies). It is additionally powerful for skin revival and tightening around the eyes. Before injecting PRP to treat hair loss, a small scalp roller with spikes is utilized to invigorate the diminishing regions. The rationale is that this makes an impression on the hair follicles to begin the healing procedure. At that point, PRP is injected over the influenced territory to additionally stimulate stem cells in the follicle. Platelet-rich plasma is injected by different minor punctures under the dermis, with or without topical nearby anesthesia. The procedure is painless if sufficient topical anesthesia is applied. At the point when PRP is injected into the harmed zone, it fortifies the tissue, causing gentle inflammation that triggers the healing cascade. As a result of this, new collagen starts to develop. As this collagen matures, it starts to shrink and tightens and reinforces the skin. Change in skin texture and tone is recognizable within 3 weeks. Full collagen recovery requires 3 months.

In PRP, activated platelets discharge numerous other bioactive proteins in charge of pulling in macrophages and mesenchymal stem cells. Inside the platelet are two sorts of granules, to be specific, alpha granules and thick bodies. Alpha granules contain the coagulating and growth factors that are discharged in the healing procedure. Regularly at the resting state, platelets require a trigger to activate and turn a participant in wound healing and hemostasis. Growth factors and different cytokines in platelets involve the following: platelet-determined growth factor, transforming growth factor, fibroblast growth factor, insulin-like growth factor 1, insulin-like growth factor 2, vascular endothelial growth factor, epidermal growth factor, interleukin 8, keratinocyte growth factor, and connective tissue growth factor. The platelets secrete growth factors, including platelet-determined growth factor and vascular endothelial growth factors. The platelet-determined growth factor is one of various growth elements or proteins that regulates cell growth and division. Specifically, it has a significant role in the formation of blood vessels (angiogenesis) and the growth of blood vessels from already existing vein tissue. The vascular endothelial growth factor is a chemical sign created by cells that invigorate the growth of fresh blood vessels. It is part of the system that restores the oxygen supply to tissues when blood circulation is deficient.

In conclusion, although the scientific information to help the legitimacy of Mesotherapy as a treatment choice in alopecia is lacking, there is an expanding enthusiasm for its utilization. Hair Mesotherapy isn’t yet endorsed in the treatment of alopecia and the current investigations give variable outcomes. In this manner, long‐term studies on a large cohort of patients are important to archive its efficacy and well-being in alopecia treatment and to standardize the treatment protocols.

Despite the expanding enthusiasm for Microneedling in the treatment of various sorts of alopecia, additionally, randomized controlled trials are required to survey the efficacy of Microneedling on alopecia.

Literature suggests PRP has a compelling tool in AGA patients. Hence, Platelet-rich plasma can be considered as an alternative treatment in AA patients not receptive to corticosteroid treatment or in the patients creating symptoms because of steroid injections.
