Review
Millions of new cancer patients receive chemotherapy each year. In addition to killing cancer cells, chemotherapy is likely to damage rapidly proliferating healthy cells, including the hair follicle keratinocytes. Chemotherapy causes substantial thinning or loss of hair, termed chemotherapy-induced alopecia (CIA), in approximately 65% of patients. CIA is often ranked as one of the most distressing adverse effects of chemotherapy, but interventional options have been limited. To date, only scalp cooling has been cleared by the US Food and Drug Administration (FDA) to prevent CIA. However, several factors, including the high costs not always covered by insurance, preclude its broader use. Here we review the current options for CIA prevention and treatment and discuss new approaches being tested. CIA interventions include scalp cooling systems (both non-portable and portable) and topical agents to prevent hair loss, versus topical and oral minoxidil, photobiomodulation therapy (PBMT), and platelet-rich plasma (PRP) injections, among others, to stimulate hair regrowth after hair loss. Evidence-based studies are needed to develop and validate methods to prevent hair loss and/or accelerate hair regrowth in cancer patients receiving chemotherapy, which could significantly improve cancer patients' quality of life and may help improve compliance and consequently the outcome of cancer treatment.

Review
Androgenetic alopecia is a condition that results in hair loss in both men and women. This can have a significant impact on a person's psychological well-being, which can lead to a decreased quality of life. We conducted a systematic review to evaluate the efficacy of using stem cells in androgenic alopecia. The search was conducted in MEDLINE via PubMed, Web of Science, and Scopus databases. The review was performed on data pertaining to the efficacy of using different types of stem cells in androgenic alopecia: quantitative results of stem cell usage were compared to the control treatment or, different types of treatment for female and male androgenetic alopecia. Of the outcomes, the density of hair was analyzed. Fourteen articles were selected for this review. During and after treatment with stem cells, no major side effects were reported by patients with alopecia. The use of stem cells in androgenic alopecia seems to be a promising alternative to the standard treatment or it could play the role of complementary therapy to improve the effect of primary treatment. However, these results should be interpreted with caution until they can be reproduced in larger and more representative samples.

The number of articles evaluating platelet-rich plasma (PRP) efficacy in androgenic alopecia (AGA) have exponentially increased during the last decade. A systematic review on this field was performed by assessing in the selected studies the local injections of PRP compared to any control for AGA. The protocol was developed in accordance with the Preferred Reporting for Items for Systematic Reviews and Meta-Analyses-Protocols (PRISMA-P) guidelines. A multistep search of the PubMed, MEDLINE, Embase, PreMEDLINE, Ebase, CINAHL, PsycINFO, Clinicaltrials.gov, Scopus database, and Cochrane databases was performed to identify studies on hair loss treatment with platelet-rich plasma. Of the 163 articles initially identified, 123 articles focusing on AGA were selected and, consequently, only 12 clinical trials were analyzed. The studies included had to match predetermined criteria according to the PICOS (patients, intervention, comparator, outcomes, and study design) approach. In total, 84% of the studies reported a positive effect of PRP for AGA treatment. Among them, 50% of the studies demonstrated a statistically significant improvement using objective measures and 34% of the studies showed hair density and hair thickness improvement, although no values or statistical analysis was described. In total, 17% of the studies reported greater improvement in lower-grade AGA, while 8% noted increased improvement in higher-grade AGA. Only 17% of the studies reported that PRP was not effective in treating AGA. The information analyzed highlights the positive effects of PRP on AGA, without major side effects and thus it be may considered as a safe and effective alternative procedure to treat hair loss compared with Minoxidil and Finasteride.

Review
Disturbances of hair follicle cycling lie at the heart of most hair growth disorders, and have dramatic effects on visible hair growth and shedding. The two common disorders due to aberration in hair follicle cycling are telogen and anagen effluvium. Though a lot of literature addresses the problem of telogen effluvium, there are not many reviews on anagen effluvium or anagen hair loss. Anagen effluvium is considered synonymous with chemotherapy-induced alopecia and other causes are rarely considered. In this review, we try to discuss the etiopathogenesis, clinical presentation, differentials, and management issues in anagen effluvium. Anagen effluvium is the abrupt loss of hairs that are in their growing phase (anagen) due to an event that impairs the mitotic or metabolic activity of hair follicle. Chemotherapy, radiation and toxic chemicals, and sometimes inflammatory diseases like alopecia areata and pemphigus are also capable of diminishing the metabolic activity of hair follicles resulting in anagen hair loss. Although it is reversible, and hair regrowth occurs after a delay of 1-3 months; sometimes it can lead to permanent alopecia and can be psychologically devastating with negative impact on individual perceptions of appearance, body image, sexuality, and self-esteem. For some patients, the emotional trauma may be so severe that it may lead to discontinuing or refusing therapy that might otherwise be beneficial. In such cases, a psychosomatic approach as well as empathic consideration of the patients concerns and fears as well as the provision of practical medical-aesthetic and styling tips are equally important and can be integrated in management.

Journal of the American Academy of... Feb 2022The current classification for alopecia areata (AA) does not provide a consistent assessment of disease severity.
BACKGROUND
The current classification for alopecia areata (AA) does not provide a consistent assessment of disease severity.
OBJECTIVE
To develop an AA severity scale based on expert experience.
METHODS
A modified Delphi process was utilized. An advisory group of 22 AA clinical experts from the United States was formed to develop this AA scale. Representatives from the pharmaceutical industry provided feedback during its development.
RESULTS
Survey responses were used to draft severity criteria, aspiring to develop a simple scale that may be easily applied in clinical practice. A consensus vote was held to determine the final AA severity statement, with all AA experts agreeing to adopt the proposed scale.
LIMITATIONS
The scale is a static assessment intended to be used in clinical practice and not clinical trials.
CONCLUSION
The final AA disease severity scale, anchored in the extent of hair loss, captures key features commonly used by AA experts in clinical practice. This scale will better aid clinicians in appropriately assessing severity in patients with this common disease.

Meta-Analysis
The aim of this study was to compare the efficacy and safety of treatment with Janus kinase inhibitors for alopecia areata, measured by change in Severity of Alopecia Tool (SALT) score. A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines was performed using Medline, EMBASE and Cochrane library. All studies investigating the efficacy of treatments for alopecia areata were included. Primary outcomes were the proportion of patients with alopecia areata achieving 30%, 50%, 75%, 90% and 100% improvement in SALT score after treatment with a Janus kinase inhibitor. A meta-analysis was performed including all randomized controlled trials investigating Janus kinase inhibitors. A total of 37 studies matched the inclusion criteria and were included. Meta-analysis was performed based on 5 randomized studies. Regarding patients with alopecia areata defined as ≥ 50% scalp hair loss, baricitinib 4 mg once daily demonstrated the highest efficacy. However, among patients with alopecia areata defined as a SALT score ≥ 50, oral deuruxolitinib 12 mg twice daily demonstrated the highest efficacy. Deuruxolitinib and baricitinib appear to be promising drugs for the treatment of alopecia areata. However, the response depends on the dosage of the drug. More randomized trials, with identical inclusion criteria and dose and duration of treatment, are required to confirm these findings.

BACKGROUND
Male baldness is very common. Its effect on individuals is extremely variable, and in some people it will have a significant adverse effect on their quality of life.
OBJECTIVE
The objectives of this article are to help general practitioners (GPs) be aware of potential health problems related to male baldness, to have an approach to assessing hair loss and to be aware of treatment options.
DISCUSSION
Male baldness is, most often, a normal occurrence, but it may have significant effects on a man's health. It may also be a pointer to other potential health issues. The GP is in the ideal position to conduct an initial evaluation, consider other health issues and advise on treatment options.

Review
Hair loss is a topic of enormous public interest and understanding the pathophysiology and treatment of various alopecias will likely make a large impact on patients' lives. The investigation of alopecias also provides important insight in the basic sciences; for instance, the abundance of stem cell populations and regenerative cycles that characterize a hair follicle render it an excellent model for the study of stem cell biology. This review seeks to provide a concise summary of the major alopecias with regard to presentation and management, and correlate these to recent advances in relevant research on pathogenesis.
