Abstract
Androgenetic alopecia (AGA) is the most prevalent type of hair loss in women and men. Recently, a European consensus group published guidelines for the diagnostic evaluation of AGA in men, women, and adolescents. This S1 guideline presents expert opinion-based recommendations for gender-dependent steps in the diagnostic procedure, which can easily be implemented in the daily clinical routine. For diagnosing AGA, detailed anamnesis and objective learning are not enough because there are several conditions mimicking this disease. Trichoscopy can be considered an important, non-invasive tool for diagnosing hair and scalp disorders that may have similar clinical signs to AGA.

[PMID: 37475557 DOI: 10.2174/1570163820666230720153607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 04/24/2023] [Accepted: 05/12/2023] [Indexed: 07/22/2023]
Abstract
BACKGROUND Nowadays, the majority of the population suffers from the problem of hair loss. It leads to disturbed mental health, lower self-confidence, and a lot more problems. A lot of the hair loss therapies available are not reliable and lead to recurrence and side effects after some time. Cannabinoids (CBD) have recently become quite popular for their benefits against hair loss. CBD oil preparations have been used both internally and externally for oral and topical use, respectively. Due to the presence of the endocannabinoid system (ECS) in the body, which naturally targets CB1 and CB2 receptors, the control of hair fall is possible. CBD is used topically for hair loss, whereas it is administered orally for the treatment and management of a medical condition, i.e., alopecia. AIM/OBJECTIVE The present review aimed to provide an in-depth study on hair loss and its management using CBD and its associated mechanisms. METHODS Electronic databases, such as ScienceDirect, Google Scholar, PubMed, Wiley, Springer, and Scopus, were thoroughly searched for information about how CBD is used, how it works, and what role it plays in treating alopecia and hair loss. RESULTS This review has highlighted the use of CBD-based hair loss therapy, and described various types of hair loss and their treatments. This review also details the phytocannabinoids and the potential mechanisms of CBD's activity against hair loss and alopecia. CONCLUSION The data obtained from the literature regarding CBD and hair loss provide a scientific basis for CBD use in alopecia. Additionally, a more precise and comprehensive study concerning CBD needs to be carried out at the pre-clinical and clinical levels.

Li WQ, Cho E, Han J, Weinstock MA, Qureshi AA. Male pattern baldness and risk of incident skin cancer in a cohort of men. Int J Cancer 2016; 139:2671-2678. [PMID: 27542665 DOI: 10.1002/ijc.30395] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2016] [Revised: 07/25/2016] [Accepted: 08/15/2016] [Indexed: 01/26/2023]
Abstract
We examined the association between male-pattern baldness and risk of incident skin cancer, including invasive melanoma, invasive squamous cell carcinoma (SCC), and basal cell carcinoma (BCC) in a prospective analysis, based on 36,032 participants from the Health Professionals' Follow-up Study. In 1992, participants reported their status of male-pattern baldness at age 45 years by choosing from five crown-view pictograms based on Norwood's classification. Diagnosis of skin cancers was reported biennially and information on melanoma and SCC was pathologically confirmed. We identified 327 melanoma cases, 1324 SCC cases, and 8438 BCC cases during the follow-up. Male-pattern baldness was not significantly associated with risk of incident melanoma, but was significantly associated with increased risk of SCC and BCC. The multivariate-adjusted hazard ratio (HR) (95% confidence interval, CI) for the highest category of baldness (frontal plus severe vertex baldness) was 1.33 (1.06-1.68) for SCC (ptrend = 0.001) and 1.23 (1.12-1.35) for BCC (ptrend < 0.0001), compared with no baldness. Analyses by body sites found significant associations between frontal plus moderate to severe vertex baldness and risk of melanoma (HR = 1.83, 95% CI: 1.01-3.34) and SCC (HR = 1.30, 95% CI: 1.02-1.66) at head and neck. The associations were particularly stronger for scalp melanoma (HR = 7.15, 95% CI: 1.29-39.42) and scalp SCC (HR = 7.09, 95% CI: 3.84-13.08), but not for non-scalp head and neck sites. Information on body sites was not available for BCC. In conclusion, male pattern baldness may be associated with increased risk of skin cancer, but the associations may only exist for those occurring at head and neck, particularly at scalp.
