ABSTRACT
BACKGROUND: Female Pattern Hair Loss (FPHL) is one of the most common types of hair loss in women. It is characterized by progressive follicular miniaturization leading to diffuse hair thinning over the midfrontal scalp with a negative impact on quality of life. Pharmacological treatments are commonly used, and hair follicle transplantation is an option for those cases with adequate donor area. Minimally invasive procedures, such as microneedling, mesotherapy, microinfusion of drugs into the scalp with tattoo machines (MMP®), and platelet-rich plasma (PRP) have been reported as adjuvant treatments. AIMS: This study aims to summarize and discuss the efficacy of minimally invasive procedures described for the management of FPHL. METHODS: Published articles indexed on the Pubmed database and Scopus that described minimally invasive procedures for the management of FPHL in humans were considered. Citations were reviewed and added for completeness. The search was for articles in English only. After excluding duplicate titles, 23 relevant articles were considered. CONCLUSION: Minimally invasive procedures are promising options and may play a role in FPHL treatment. They can be used as adjunctive therapy for FPHL, in case of poor response to clinical therapy, or when patients prefer other care than the standard. We reinforce that these methods should be performed by an experienced medical professional following strict aseptic techniques. However, microneedling, mesotherapy, MMP, and PRP lack standardization and are supported by a low level of evidence yet. For the future, larger randomized clinical trials are essential to determine the efficacy and optimal protocols for these treatments.

Female pattern hair loss (FPHL) is the most common form of alopecia in women. FPHL may compromise body image and strongly affect self-esteem, negatively impacting quality of life. Currently, the only Food and Drug Administration (FDA) approved drug for its treatment is topical minoxidil, with a variable response rate. Recently, a few studies in FPHL have pointed out bicalutamide as an emergent selective androgen receptor antagonist with a favorable safety and tolerability profile. This review aimed to summarize and discuss the key information on this new therapy for FPHL. Bicalutamide has no diuretic effect. It does not cross the blood-brain barrier, and it has little effect on serum luteinizing hormone. Additionally, bicalutamide was found to be effective on women presenting with other features of hyperandrogenism such as seborrhea, acne, and hirsutism with mild and well-tolerated adverse effects. Despite the high prevalence and psychosocial impairment, FPHL treatment remains challenging. Therefore, although future prospective, comparative, randomized clinical trials are essential to establish the ideal dose and efficacy of the drug, oral bicalutamide appears to be a promising option to expand the arsenal of FPHL treatment.

Dissecting cellulitis (DC) is a chronic inflammatory primary neutrophilic scarring alopecia. It predominantly affects the vertex and occipital regions of Afro-descendent men. Female DC is uncommon, and little is known about this condition in childhood. This paper reports a pediatric female case of DC with an excellent therapeutic response to low-dose oral isotretinoin.

Hair represents an important aspect of human individuality. The possibility of having an easy to handle hairstyle and changing it from time to time promoted an increasing search for chemical hair transformations, including permanent wavings (PW). PW is the chemical process used to convert straight into curly hair. Significant findings have been made in this field within the last three decades. In the past few years, PW has come back up to date, helping to define curls in wavy and curly hair and to create waves in straight hair. "Afro permanent" and "Beach waves" are some popular names for these new uses of PW. The primary safety concerns for PW generally arise from misuse or failure to comply with the product's usage instructions. Skin irritation, hair breakage, oral toxicity, sensitization, and scarring alopecia have been reported in the literature. Therefore, dermatologists need to understand well this matter to properly advise patients on how to get the best outcome without hazards. This review aims to discuss the main types of reducing agents used, the different techniques, the consequences to hair shafts, and the most important patients' recommendations on this topic.

O nevo sebáceo de Jadassonh é um nevo epidérmico composto por glândulas sebáceas de coloração rosa ou amarelada, que pode apresentar o desenvolvimento de várias neoplasias benignas e malignas. É uma das malformações anexais que ocorre com maior frequência nas crianças1,2. Clinicamente aparece como uma placa bem definida de alopecia no couro cabeludo, face ou colo. Está presente desde o nascimento ou pode surgir alguns anos mais tarde1. Apresentamos o caso de um nevo sebáceo de Jadassohn no couro cabeludo a partir do qual um carcinoma basocelular se desenvolveu e foi diagnosticado com o auxílio da dermatoscopia.
