ABSTRACT

BACKGROUND: Foremost fine hairs in the frontal hairline region are critical in hair transplantation for hairline correction (HTHC) in women. However, there are few studies on a nonsurgical revisionary method for improving an unnatural foremost hairline with thick donor hairs resulting from a previous HTHC. OBJECTIVE: To investigate the efficacy and safety of using a hair removal laser (HRL) system to create fine hairs in Asian women with thick donor hairs. METHODS: Through a retrospective chart review, the HRL parameters, hair diameter (measured with a micrometer before and after the procedures), subjective results after the procedures, adverse effects, and the number of procedures were investigated. The reduction rate of the hair diameter was calculated. RESULTS: Twenty-four women who received long-pulse Neodymium-Doped:Yttrium Aluminum Garnet therapy after HTHC were included. The parameters were as follows: delivered laser energy, 35~36 J/cm2; pulse duration, 6 ms; and spot size, 10 mm. The mean number of laser sessions was 2.6. The mean hair diameter significantly decreased from 80.0+/-11.5 microm to 58.4+/-13.2 microm (p=0.00). The mean rate of hair diameter reduction was -25.7% (range, -44.6% to 5.7%). The number of laser sessions and the hair diameter after the procedures showed a negative correlation (r=-0.410, p=0.046). Most of the patients (87.5%) reported subjective improvement of their hairlines. Most complications were transient and mild. CONCLUSION: HRL can be an alternative method for creating fine hairs and revising foremost hairline in Asian women with thick donor hairs.

ABSTRACT

Matridex(R) is an injectable skin filler that's composed of a mixture of cross linked hyaluronic acid and dextranomer particles, and it was recently developed for soft tissue augmentation. To the best of our knowledge, there have been few previous reports on complications associated with Matridex. We report here on a delayed inflammatory reaction to an injection of Matridex in the glabellar fold, and this developed five weeks after the injection and it lasted more than a year. The patient was treated with oral doxycycline and intralesional injection of triamcinolone acetonide; this resulted in almost complete resolution of the lesion. The patient should be informed of the potential complications with the use of injectable fillers before treatment, for it could lead to undesirable aesthetic consequences.

ABSTRACT

BACKGROUND: Although it is well known that transforming growth factor beta (TGF-beta) may induce catagen change of hair follicles and inhibit hair growth, it is still unclear which subtype of TGF-beta and its specified receptor might be expressed in human hair follicles of androgenetic alopecia (AGA) patients. OBJECTIVE: To delineate precise expression of TGF-beta subtype in human hair follicles of androgenetic alopecia patients. METHODS: Immunohistochemical studies were performed on paraffin sections of human hair follicles by applying type 1, 2, and 3 TGF-beta antibodies and type I and II receptor antibodies. We ascertained the expression of TGF-beta subtype in hair follicles of androgenetic alopecia patients. We also compared the expression pattern of each type of TGF-beta receptor. We evaluated the change of TGF-beta expression of hair follicles in the catagen phase. RESULTS: TGF-beta1 was well-expressed in the outer area of the inner root sheath (IRS) or dermal connective sheath area. TGF-beta2 was commonly expressed in the inner 1/2 of the outer root sheath (ORS). TGF-beta3 was expressed in the hair cortex, IRS, and cuticle in normal hair follicles obtained from both the vertex and occipital area. On the contrary, in specimens from AGA, the enhanced expression of type 2 TGF-beta or type II receptor was observed in the vertex area (bald) compared to the occipital area (non bald). When the expression patterns of TGF-beta 1, 2, and 3 were compared between anagen and catagen phases, TGF-beta2 and 3 were positively expressed in the epithelial strands and secondary hair germs in the catagen phase. The immunoreactivities of TGF-beta 1 and 2 were intensified in the ORS areas of the catagen phase. CONCLUSION: The expression of type 1, 2 TGF-beta and type I and II receptors in follicular epithelial cells might be related to catagen induction and development of androgenetic alopecia of human hair in vivo.

ABSTRACT

BACKGROUND: Hair loss is a very common disorder and the number of patients is known to be increasing. Female pattern hair loss (FPHL) is not only a medical problem but also a very severe psychosocial problem for many female patients. Anti-androgen drugs, mineral supplements and topical minoxidil have all been used for the treatment of FPHL. However they do not always achieve successful results and there is still much need for more effective therapy. OBJECTIVE: The purpose of this 18-week, double-blind, placebo-controlled, randomized clinical trial was to investigate the efficacy and safety of a new topical agent, AP-FHG0604T, in the treatment of FPHL. METHODS: A total of 33 women with FPHL (mean age: 33.4 years old) applied either a topical AP-FHG0604T solution (n=17), or placebo (vehicle for AP-FHG0604T solution; n=16) twice daily. Efficacy was evaluated by phototrichogram, investigator's photographic and patient's subjective assessments. All adverse effects were reported during the study. RESULTS: After 18 weeks of therapy, topical AP-FHG0604T treatment showed a significant improvement compared to baseline values of total hair count, non-vellus hair count, and linear hair growth rate. In the placebo group, non-vellus hair count and ratio of anagen hair significantly decreased. The change rates of total hair count and non-vellus hair count in the AP-FHG0604T group were significantly higher than those in the placebo group. Neither investigator's photographic assessments nor patient's subjective assessments of hair growth showed statistically significant differences between the AP-FHG0604T group or the placebo group. Some patients who used AP- FHG0604T complained of local irritation during the study, but the irritation was so mild that they did not need any treatment for this. CONCLUSION: We conclude that AP-FHG0604T is a safe and efficient topical agent which can be used as another treatment of choice for FPHL, as shown by objective assessment with phototrichogram.
