The tricky "trichs" in dermatology!

CBD: A Potential Lead against Hair Loss, Alopecia, and its Potential Mechanisms

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.

Trichologist, Dermatotrichologist, or Trichiatrist? A Global Perspective on a Strictly Medical Discipline

Few dermatologic problems carry as much emotional overtones as the complaint of hair loss. The best way to alleviate the distress related to hair loss is to effectively treat it. In fact, one of the oldest medical professions is the Egyptian physician who specialized on diseases of the head. And yet, from ancient Egypt down to modern times, human hair has been the object of superstition and mystery. Remarkably and despite the genuine advances in effective medical treatments, hair cosmetics, and surgical procedures, phony hair loss solutions continue to be marketed with an amazing success. In 1860, a quasi-scientific interest in hair loss and hair care originated in a London barbershop and became known as trichology, with the Institute of Trichologists being founded. Other corporations successively followed internationally, but it was only in 2010 that the term dermatotrichologist was proposed for board-certified dermatologists dealing with the scientific study of the hair and scalp, in contrast to the trichologist who is rather associated with laity and cosmetics than with medical professionalism, or - worse - offers opportunities to possible imposters with a primary commercial interest. The new term "trichiatrist" is proposed, literally meaning the "medical treatment of the hair," to designate the strictly medical professional dealing with the hair and scalp in health and disease. Trichiatrists differ from trichologists by virtue of being physicians. The quality and stringency of their graduate medical training is identical to that of other physicians.
