Dense-packing hair grafting technique for restoration of cicatricial alopecia

OBJECTIVE: To investigate the possibility of using dense-packing hair grafting technique for restoration of cicatricial alopecia. METHODS: Under local anesthesia, a scalp strip was harvested from the back of the head. A series of micro-grafts with 1-3 hairs and mini-grafts with 4-6 hairs were created from this strip. In the scarring recipient area, micro-slots were made with a 18 G needle for the micro-grafts and mini-slits were made with a No. 64 mini-blade for the mini-grafts. The grafts were then implanted into these holes. RESULTS: Ninety-six patients with 128 bald scarring areas, resulted from burn, trauma or infection, were treated with the above-mentioned technique from April. 1998 to February. 2000. All of the patients were satisfied with the appearance. In the micro-graft area, the graft density reached 10-15 mini-grafts/cm2 per session. In the micro-graft area, the graft density reached 16-19 micro-grafts/cm2 per session. Postoperative following-up for more than 1 year showed that the grafted hairs were growing well with 90%-95% survival of the hair. One third of the patients obtained satisfactory results with only one session. Two thirds of the patients needed the second session to improve the appearance. CONCLUSIONS: The dense-packing hair grafting technique is a simple, safe and effective method for hair restoration surgery. It is not only used for male pattern baldness, but could also be applied for restoration of cicatricial alopecia.

The effect of hair loss on quality of life.

BACKGROUND: The aim of this study was to quantify the effect of hair loss on quality of life. Patients were recruited from an alopecia support group, and were assessed using the Dermatology Life Quality Index (DLQI) and an adapted version of the DLQI. Financial utility questions, an abbreviated version of the Center for Epidemiologic Studies Depression Scale and open-ended questions were also used. OBSERVATIONS: Seventy (90% response rate) questionnaires were returned. DLQI scores in responders with hair loss (mean score = 8.3, SD = 5.6, range 0-23, n = 70) were similar to those recorded in severe psoriasis. The hair loss continued to have a significant impact on life quality well after the initial event (median duration of hair loss = 138 months +/- 114; range 7-588, n = 70). Forty per cent of patients also felt dissatisfied with the way in which their doctor dealt with them. CONCLUSIONS: This study specifically identifies the feelings of loss of self-confidence, low self-esteem and heightened self-consciousness in people affected by hair loss.

Female alopecia: the mediating effect of attachment patterns on changes in subjective health indicators.

Background The interrelationship between female alopecia and psychological disorders is complex, with a range of psychosocial consequences, but also antecedents. Psychosocial antecedents are to a large extent interpersonal and can be assumed to have a mediating effect on health care utilization and subjective health. Objectives To analyse whether changes in health-related quality of life (QoL) are mediated by relational or attachment styles and whether these styles are associated with a particular, dysmorphophobic type of alopecia. Methods Seventy-four women with androgenetic and diffuse alopecia underwent psychological assessment at the first consultation at a university clinic and at 2 months' follow-up. Attachment styles were evaluated by an observer rating scale. As a primary endpoint a disease-specific QoL instrument was employed. Results Findings indicated an association between patients with nonvisible hair loss and the ambivalent attachment style. Global clinical impressions and attachment indicators, e.g. attachment security and coping strategies, showed significant contributions in predicting changes in the QoL scales 'self-esteem' and 'emotions'. Conclusions These findings suggest that attachment security may be one of the underlying mechanisms mediating subjective health and that a specific attachment vulnerability can be identified in a subgroup of patients with female alopecia. Future studies will have to focus on the relevance of attachment patterns in the doctor-patient relationship and on psychotherapeutic interventions.

Transplants from balding and hairy androgenetic alopecia scalp regrow hair comparably well on immunodeficient mice.

Human hair follicles were grafted onto 2 strains of immunodeficient mice to compare the regeneration potential of vellus (miniaturized, balding) and terminal (hairy, nonbalding) follicles from males and a female exhibiting pattern baldness. Each mouse had transplants of both types of follicles from a single donor for direct comparison. Grafted follicles from 2 male donors resulted in nonsignificant differences in mean length (52 mm vs 54 mm) and mean diameter (99 microm vs 93 microm) at 22 weeks for hairs originating from balding and hairy scalp, respectively, corresponding to 400% versus 62% of the mean pretransplantation diameters. Follicles from the female donor transplanted to several mice also resulted in nonsignificant differences in length (43 mm vs 37 mm) for hairs from balding and hairy scalp, respectively, during a period of 22 weeks. The mean diameter of the originally vellus hairs increased 3-fold, whereas the terminal hairs plateaued at approximately 50% of pretransplantation diameter, resulting in a final balding hair volume double that of the nonbalding hairs. This report shows that miniaturized hair follicles of pattern alopecia can quickly regenerate once removed from the human scalp and can grow as well as or better than terminal follicles from the same individual.

Hair growth is a sophisticated biological process, which is still not thoroughly understood. A multitude of therapeutic measures, including drugs, surgery, and suppelements have been made available, and used. However, due to the diversity of the problems underlying hair loss, there is no single solution for all hair loss cases. Most of chemical drugs and hair transplantation surgeries are not free from varying degrees of undesirable side effects on health.

Hair Million is an alternative solution to hair loss problems. Anecdotally, it shows prositive results and improvement especially for age-related hair thinning and hair loss for a fraction of people who take it. We do not know the mechanisms of action as to how Hair Million works to help stop hair loss, and promote hair growth. We only know by anecdotal observations. There has been no clinical trials nor placebo controlled statistical analysis on the efficacy of Hair Million on hair loss and hair growth.

DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones) or estrogens (female hormones) in the cells.
