Abstract
The soft tissues have a considerable impact on whether the results of facial feminization surgery are favorable. Complications or suboptimal results related to the soft tissue may be due to poor choice of surgical approach, improper execution of the surgical technique, a lack of assistance when resuspending the soft tissues during closure, or deficient readaptation of the overlying soft tissue to the new bone contour. This article identifies the possible poor soft-tissue outcomes that may occur after facial feminization bone surgery, describing strategies to prevent them and treatment alternatives.

Triethylene Glycol Squalene Improves Hair Regeneration by Maintaining the Inductive Capacity of Human Dermal Papilla Cells and Preventing Premature Aging. ACS Pharmacol Transl Sci 2024; 7:2006-2022. [PMID: 39022356 PMCID: PMC11249624 DOI: 10.1021/acsptsci.4c00114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 05/25/2024] [Accepted: 05/28/2024] [Indexed: 07/20/2024]
Abstract
De novo hair follicle (HF) regeneration, achieved through the replenishment of the dermal papilla (DP), acknowledged as the principal orchestrator of the hair growth cycle, is emerging as a prospective therapeutic intervention for alopecia. Nonetheless, multiple attempts have shown that these cells lose key inductive properties when cultured in a two-dimensional (2D) monolayer, leading to precocious senescence engendered by oxidative stress and inflammatory processes. Consequently, the three-dimensional (3D) spheroid technique is presently widely employed for DP cell culture. Nevertheless, substantiating the regenerative potential of these cells within the hair follicle (HF) milieu remains a challenge. In this current study, we aim to find a new approach to activate the inductive properties of DP cells. This involves the application of hair-growth-stimulating agents that not only exhibit concurrent protective efficacy against the aging process but also induce HF regeneration. To achieve this objective, we initially synthesized a novel highly amphiphilic derivative derived from squalene (SQ), named triethylene glycol squalene (Tri-SQ). Squalene itself is a potent antioxidant and anti-inflammatory compound traditionally employed as a drug carrier for alopecia treatment. However, its application is limited due to its low solubility. Subsequently, we applied this newly synthesized derivative to DP cells. The data obtained demonstrated that the derivative exhibits robust antioxidant and anti-inflammatory activities while concurrently promoting the expression of genes associated with hair growth. Moreover, to further assess the hair regrowth inductive properties of DP cells, we cultured the cells and treated them with Tri-SQ within a 3D spheroid system. Subsequently, these treated cells were injected into the previously depilated dorsal area of six-week-old male C57BL/6 mice. Results revealed that 20 days postinjection, a complete regrowth of hair in the previously hairless area, particularly evident in the case of 3D spheroids treated with the derivative, was observed. Additionally, histological and molecular analyses demonstrated an upregulation of markers associated with hair growth and a concurrent decrease in aging hallmarks, specifically in the 3D spheroids treated with the compound. In summary, our approach, which involves the treatment of Tri-SQ combined with a 3D spheroid system, exhibited a notably robust stimulating effect. This effect was observed in the induction of inductive properties in DP cells, leading to HF regeneration, and concurrently, it demonstrated an inhibitory effect on cellular and follicular aging.

Abstract
Gender-affirming hormone therapy (GAHT) leads to changes in body composition, secondary sex characteristics and in the distribution and pattern of hair growth. Transgender individuals undergoing GAHT may experience altered hair growth patterns that may be affirming and desirable, or undesirable with a subsequent impact on their quality of life. Given increasing numbers of transgender individuals commencing GAHT worldwide and the clinical relevance of the impact of GAHT on hair growth, we systematically reviewed the existing literature on the impact of GAHT on hair changes and androgenic alopecia (AGA). The majority of studies used grading schemes or subjective measures of hair changes based on patient or investigator's examination. Very few studies used objective quantitative measures of hair parameters but demonstrated statistically significant changes in hair growth length, diameter and density. Feminizing GAHT with estradiol and/or antiandrogens in transgender women may reduce facial and body hair growth and also can improve AGA. Masculinizing GAHT with testosterone in transgender men may increase facial and body hair growth as well as induce or accelerate AGA. The impact of GAHT on hair growth may not align with a transgender person's hair growth goals and specific treatment for AGA and/or hirsutism may be sought. Further research on how GAHT affects hair growth is required.

Abstract
OBJECTIVE To observe the efficacy of unilateral subcutaneous injection of botulinum toxin A combined with finasteride and minoxidil in the treatment of androgenic alopecia. METHODS Thirty-seven patients with androgenic alopecia were treated with finasteride and minoxidil as standard therapy and were randomly assigned to subcutaneous injections of botulinum toxin A in one hemisphere of the head at the beginning of a 6-month treatment. Before treatment, 3 months after treatment, and 6 months after treatment, the patient's head hair growth was photographed and evaluated. RESULTS After 3 and 6 months of treatment, hair density of the treated androgenic alopecia patients was higher than before treatment (p < 0.05), and the hair density of the botulinum toxin A injection side was higher than that of the control side (p < 0.05). After 6 months of treatment, the response rate of botulinum toxin A combined with finasteride and minoxidil was 77.5%, with no significant side effects observed. CONCLUSION Finasteride and minoxidil have a significant effect on androgenic alopecia, and the effect is further increased after combined with botulinum toxin A subcutaneous injection.

Abstract
The dermal papilla comprises mesenchymal cells in hair follicles, which play the main role in regulating hair growth. Maintaining the potential hair inductivity of dermal papilla cells (DPCs) and dermal sheath cells during cell culture is the main factor in in vitro morphogenesis and regeneration of hair follicles. Using common methods for the cultivation of human dermal papilla reduces the maintenance requirements of the inductive capacity of the dermal papilla and the expression of specific dermal papilla biomarkers. Optimizing culture conditions is therefore crucial for DPCs. Moreover, exosomes appear to play a key role in regulating the hair follicle growth through a paracrine mechanism and provide a functional method for treating hair loss. The present review investigated the biology of DPCs, the molecular and cell signaling mechanisms contributing to hair follicle growth in humans, the properties of the dermal papilla, and the effective techniques in maintaining hair inductivity in DPC cultures in humans as well as hair follicle bioengineering.

Abstract
Drug-based monotherapy provides limited clinical benefits in polygenic disorders, such as androgenetic alopecia. Possible benefits must be measured against non-trivial risks of negative side effects. Several well-controlled, peer-reviewed, basic science studies have demonstrated novel mechanisms of action and potential utility for natural-based phytochemicals in the treatment of androgen-mediated disorders, including androgenetic alopecia. Yet, due to phytochemical instability, volatility, and incompatibility, the bridge from in vitro potential to clinical efficacy remains largely unmet. Recent advances in nanomaterial manipulation provide enhanced platforms, such as cyclodextrins, in which these phytochemicals may be enveloped and delivered without triggering the loss of intended function. Unexpected, positive results of an uncontrolled case series for a cyclodextrin-enabled, natural-based formula containing γ linolenic acid, β-Sitosterol, epigallocatechin gallate, and genistein, administered concomitantly via oral and topical form in two androgenetic alopecia-affected, male subjects over the course of 270 days were found. At baseline, significant baldness in the vertex scalp of both subjects was observed. Subsequent 90-day time points demonstrated marked hair thickening. On treatment day 270 (conclusion), scalp hair loss was no longer evident in either patient. Particularly in the setting of a disorders, such as androgenetic alopecia, nano-complexed, botanically-based compositions may offer beneficial adjunctives or alternatives to traditional drug-based/surgical medical treatments.
