Mauro Barbareschi
Even if minoxidil has been known for over 30 years as "hair growth stimulator" the precise mechanism of its action is not completely elucitated. Minoxidil shortens telogen, accelerates telogen-exogen phase and causes the premature entry of resting hair follicles into anagen phase. Moreover, minoxidil increases hair follicle size. A large part of hair treatment scientific literature confirms the efficacy of topically applied minoxidil in humans. In particular, patients treated with minoxidil showed a significant increase in "non vellus" hair count starting from baseline...

Keratin hydrolysates (KHs) are established standard components in hair cosmetics. Understanding the moisturizing effects of KH is advantageous for skin-care cosmetics. The goals of the protocol are: (1) to process chicken feathers into KH by alkaline-enzymatic hydrolysis and purify it by dialysis, and (2) to test if adding KH into an ointment base (OB) increases hydration of the skin and improves skin barrier function by diminishing transepidermal water loss (TEWL). During alkaline-enzymatic hydrolysis feathers are first incubated at a higher temperature in an alkaline environment and then, under mild conditions, hydrolyzed with proteolytic enzyme...

The objective of this study is to evaluate of rice bran mineral extract (RBM) increases the expression of anagen-related molecules in human dermal papilla (DOCs). Four treatment groups were established to evaluate the efficacy of RBM, including a negative control, positive control (ascorbic acid), RBM and ortho-silicic acid (Si(OH)4) (OSA) group. Three days after the DPCs were administered the various treatments, western blot analysis showed that type I collagen expression was increased 2.5-fold in the OSA group and 4-fold in the RBM group, and ALP expression was increased 1...

Fatty acid ethyl esters (FAEE) are direct metabolites of ethanol and have been shown to be suitable markers for the evaluation of alcohol consumption. Previous research has suggested that the regular use of alcohol containing cosmetic products can influence the concentration of FAEE detected in hair. In this study we investigated the influence of alcohol containing and alcohol free hair cosmetics (hairspray and waxes) on the FAEE concentrations in hair. The effect of cosmetic treatment was measured against the impact on ethyl palmitate in isolation as compared to the sum of four esters...

Dimethiconol and its esters and reaction products are used in cosmetics as either skin-conditioning agents or hair-conditioning agents. The Cosmetic Ingredient Review (CIR) Expert Panel reviewed relevant data and concluded that these ingredients are safe in the present practices of use and concentration described in this safety assessment. While there is an absence of data on reproductive and developmental toxicity and limited tumorigenicity and toxicokinetics data, the Panel reasoned that these ingredients would not be absorbed through the skin, obviating concern over potential reproductive and developmental toxicity or carcinogenicity...

A risk assessment of benzalkonium chloride (BAC) was conducted based upon its toxicological profile and exposure evaluation. Since 1935, BAC has been used in a wide variety of products such as disinfectants, preservatives, and sanitizers. It is well-established that BAC is not genotoxic nor does it display tumorigenic potential, but safety concerns have been raised in local usage such as for ocular and intranasal applications. The Foundation of Korea Cosmetic Industry Institute (KCII) reported that in a hair conditioner manufactured as a cosmetic or personal product in South Korea, BAC was present at concentrations of 0...

Ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEEs) in hair are effective direct biomarkers of ethanol ingestion, whose analytical determination can be used to discriminate between chronic and occasional ethanol intake. Ethanol is a compound widely used in some workplaces (e.g., clinics, hospitals) and is present in considerable amounts in mouthwash for oral cleaning, medications, cosmetic products, hydro-alcoholic disinfectants and antiseptics for hands. This study examined the ethyl alcohol exposure derived from hand disinfectants (in gel form) by simulating the typical occupational situation of medical-health workers (healthcare workers, nurses, surgeons, etc...

Men are interested in reducing signs of aging, while maintaining a masculine appearance. A chief concern among men is maintenance of scalp hair. Men are also concerned with reducing under eye bags and dark circles. The concern of feminization is of significant importance. Neuromodulators remain the most common cosmetic procedure performed in men. Men often prefer a reduction in facial rhytids, as opposed to elimination of the lines. Softening facial lines in men is meant to maintain an appearance of wisdom, without appearing fragile...

Men of all races are currently more open to requesting and undergoing treatments for a plethora of cosmetic concerns. Among the most common goals are procedures that combat the signs of aging, rejuvenate the skin, even out the color tone, address textural issues such as acne scarring, and improve hair disorders. Given the differences in cultural ideals and anatomic/physiologic differences in ethnic skin, it is important for physicians to be aware and sensitive to the nuances required when providing consultation and treating non-Caucasian men...

Body dysmorphic disorder (BDD) is characterized by excessive preoccupation with a slight or imagined defect in one's physical appearance, believing they look ugly, abnormal or deformed. While the most common preoccupations focus on the skin, hair and nose, any part of the body may be involved. Preoccupations are intrusive, time-consuming and hard to control. Repetitive behaviors are performed in response to the preoccupations. BDD is associated with marked impairment in socio-professional functioning, poor quality of life and high suicide rates...

Significant skin pigmentation changes occur when patients suffer deep burn injuries. These pigmentation disorders may cause not only cosmetic and psychological issues, but more importantly it increases the risk of skin cancer or photoaging. Severe burns significantly effect on the process of repigmentation as the pigmentation is tightly regulated by cell proliferation and differentiation of melanocytes and melanocyte stem cells which are housing in the epidermis and hair follicles of the skin. In the present review, we discuss the possible mechanisms to replenish the melanocytes from the healthy epidermis and hair follicles surrounding burn wounds...

<p>Gender plays a significant role in determining facial anatomy and behavior, both of which are key factors in the aging process. Understanding the pattern of male facial aging is critical when planning aesthetic treatments on men. Men develop more severe rhytides in a unique pattern, show increased periocular aging changes, and are more prone to hair loss. What also needs to be considered when planning a treatment is what makes men beautiful or "man-some". Male beauty strikes a balance between masculine and feminine facial features...

The Cosmetic Ingredient Review (CIR) Expert Panel assessed the safety of diethanolamine and its salts as used in cosmetics. Diethanolamine functions as a pH adjuster; the 16 salts included in this rereview reportedly function as surfactants, emulsifying agents, viscosity increasing agents, hair or skin conditioning agents, foam boosters, or antistatic agents. The Panel reviewed available animal and clinical data, as well as information from previous CIR reports. Since data were not available for each individual ingredient, and since the salts dissociate freely in water, the Panel extrapolated from previous reports to support safety...
