Causes of hair loss and the developments in hair rejuvenation

INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 1 2002
D. H. Rushton
Synopsis Hair is considered to be a major component of an individual's general appearance. The psychological impact of hair loss results in a measurably detrimental change in self-esteem and is associated with images of reduced worth. It is not surprising that both men and women find hair loss a stressful experience. Genetic hair loss is the major problem affecting men and by the age of 50, up to 50% will be affected. Initial attempts to regenerate the lost hair have centred on applying a topical solution of between 2% to 5% minoxidil; however, the results proved disappointing. Recently, finasteride, a type II 5, reductase inhibitor has been found to regrow a noticeable amount of hair in about 40% of balding men. Further developments in treatments have lead to the use of a dual type I and type II inhibitor where 90% of those treated regrow a noticeable amount of hair. In women the major cause of hair loss before the age of 50 is nutritional, with 30% affected. Increased and persistent hair shedding (chronic telogen effluvium) and reduced hair volume are the principle changes occurring. The main cause appears to be depleted iron stores, compromised by a suboptimal intake of the essential amino acid l -lysine. Correction of these imbalances stops the excessive hair loss and returns the hair back to its former glory. However, it can take many months to redress the situation. Résumé Les cheveux sont considérés comme étant une composante majeure de l'aspect général d'un individu. L'impact psychologique de la perte des cheveux conduit à une diminution mesurable de l'estime de soi et s'associe à des images de contexte négatif. Il n'est pas surprenant que les hommes comme les femmes ressentent la perte de cheveux comme une expérience stressante. La perte génétique des cheveux est le problème principal qui touche les hommes et autour de l'âge de 50 ans, jusqu'à 50% seront concernés. Les premières tentatives de régénération des cheveux perdus se sont focalisées sur l'application topique d'une solution comprenant entre 2% et 5% de minoxidil; cependant, les résultats se sont avérés décevants. Récemment, le finastéride, un inhibiteur de la 5,-réductase de type II s'est avéré permettre la repousse d'une quantité significative de cheveux chez environ 40% des hommes dégarnis. Les développements ultérieurs des traitements ont conduit à l'utilisation d'un inhibiteur associant type I et type II pour lequel 90% des personnes traitées constatent une repousse significative des cheveux. Chez les femmes la cause principale de la perte des cheveux avant l'âge de 50 ans est d'origine nutritionnelle, avec 30% de la population affectée. Une perte de cheveux persistante et croissante (telogen effluvium chronique) et un volume des cheveux réduit sont les principaux effets qui se produisent. La cause principale semble être des réserves de fer épuisées, associées à une prise insuffisante de l'acide aminé essentiel L-lysine. La correction de ces déséquilibres stoppe la perte excessive de cheveux et rend aux cheveux leur éclat d'antan. Cependant, plusieurs mois peuvent être nécessaires pour redresser la situation.

Abstract Background, Tinea pedis is a common dermatophyte infection with frequent recurrences. Terbinafine (presently used as a 1-week topical treatment of tinea pedis) is now available in a novel topical solution (film-forming solution , FFS), developed to allow single application. Objectives, To demonstrate the efficacy and safety of terbinafine 1% FFS in a randomized, double-blind, placebo-controlled, phase III trial, and to determine relapse or re-infection rate of tinea pedis at 12 weeks. Patients/methods, Fifty-four centres (27 in France; 27 in Germany) enrolled 273 evaluable patients (2 : 1 randomization). Patients applied terbinafine 1% FFS or placebo only once between, under and over the toes, soles and sides of both feet. Efficacy assessments included direct microscopy, mycological culture, and clinical signs and symptoms at baseline, and at weeks 1, 6 and 12 after the single drug application. Results, Effective treatment (negative mycology plus absent/minimal symptoms) at week 6 in the terbinafine 1% FFS group was 63%; vehicle was 17% (P 0.0001). Mycological cure was 72% in the terbinafine group and 21% in the placebo (P 0.0001) at week 6. Clinical signs/symptoms decreased significantly in the active group compared to the placebo. The self-assessment of itching and burning sensation by the patient showed a clear reduction in symptoms starting 15 min after treatment application (this could be attributed to the cooling effect of the FFS). Recurrence (positive culture at 3 months) occurred in 12.5% of the effectively treated patients at week 6 in the terbinafine group. FFS was well tolerated. Conclusion, Terbinafine 1% FFS, single dose application is an effective, safe and convenient treatment for tinea pedis. The relapse/re-infection rate 3 months after the end of single-dose therapy is similar to that previously demonstrated in a study using terbinafine 1% cream for 7 days. [source]


Hypertrichosis in females applying minoxidil topical solution and in normal controls

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 3 2003
RPR Dawber
ABSTRACT Background, Hypertrichosis has been reported more frequently in females than in males who use minoxidil topical solution (MTS) for the treatment of androgenetic alopecia (AGA). This article examines the occurrence of MTS-induced hypertrichosis in females. Methods, Data from placebo-controlled clinical trials in females (up to 5% MTS) were analysed based on spontaneous reports of hypertrichosis/facial hair and investigators' inquiries (solicited) about the presence of any new hair growth on body parts other than the scalp. A postmarketing drug surveillance database for MTS was also examined for reports of hypertrichosis/facial hair. Results, In the clinical trials involving a total of 1333 females, spontaneous reports of hypertrichosis/facial hair were noted for 50 (4%) females in a dose-related pattern of response (5% MTS > 2% MTS > placebo). Nine females (seven and two in the 5% MTS and 2% MTS groups, respectively) discontinued treatment because of hypertrichosis/facial hair. Solicited reports of excessive hair growth (primarily facial) also showed a dose-related pattern of response. Post-marketing data showed a lower occurrence (0.5%) of hypertrichosis/facial hair than in the clinical trials. Of interest, in one clinical trial, 27% of the females enrolled (MTS and placebo treated) had facial hair growth reported at baseline. Conclusions, Females with some hirsutism are particularly prone to seek treatment for AGA, and this may explain the high occurrence of hypertrichosis/facial hair found in the MTS clinical trials. Furthermore, some demographic groups of females are prone to develop facial hair and the problem of unwanted facial hair growth seems to be underestimated. Some females may have hair follicles that are very sensitive to MTS and should use the lowest strength of MTS (2%) to help avoid unwanted hair growth. The hypertrichotic effect of MTS on other sites than the scalp, including the face, is reversible and does not always require discontinuation of therapy. [source]


Ability of N -acetylcarnosine to protect lens crystallins from oxidation and oxidative damage by radical probe mass spectrometry (RP-MS)

RAPID COMMUNICATIONS IN MASS SPECTROMETRY, Issue 19 2010
Ji-won Ha
The application of Radical Probe Mass Spectrometry based on protein footprinting studies is described to investigate the effectiveness of the antioxidant N -acetylcarnosine (NAC) in preventing oxidative damage to lens crystallins present in the eye of mammals. Despite separate clinical trials which have reported the benefit of administering NAC to the eye as a 1% topical solution for the treatment of human cataract, no evidence was found to suggest that the antioxidant had any significant direct effect on reducing the levels of oxidation within the most abundant lens crystallins, , and ,-crystallin, at the molecular level at increasing concentrations of NAC. The results of this laboratory study suggest that the therapeutic benefit demonstrated in clinical trials is associated with the nature or formulation of the topical solution and/or that the mode of action of NAC as an antioxidant is not a direct one.

Abstract. Purpose:,Topical steroid use is usually avoided in cases of corneal epithelial defect. We evaluated the effect of topical steroid treatment on corneal epithelial healing after epithelial debridement in vitreoretinal surgery. Methods:,Our study population included 85 eyes undergoing vitreoretinal surgeries in our clinic. We prospectively compared the duration of corneal epithelial wound healing in 43 eyes in which topical dexamethasone was used with that in 42 eyes in which topical dexamethasone was not used in the early postoperative period after epithelial debridement. Factors that may retard corneal epithelial healing, including pre- and intraoperative topical solutions, median operative time, the presence of diabetes mellitus, prior ocular surgeries, pseudophakia, aphakia and the presence of intraocular gas or silicone oil in aphakic patients, were not significantly different between the two groups. Results:,The mean corneal epithelial defect closure time was 59.7 ± 2.6 hours (mean ± SEM) in the group receiving topical steroid treatment, and 61.9 ± 2.6 hours in the group that did not receive steroids. Conclusion:,Topical dexamethasone administered five times/day did not significantly retard corneal epithelial healing in subjects undergoing vitreoretinal surgery with postoperative topical steroid treatment, compared with subjects who did not receive steroid treatment.
