Efficacy and tolerance of a scalp-cooling system for prevention of hair loss and the experience of breast cancer patients treated by adjuvant chemotherapy.

The applicability and efficacy of a scalp cooling system were studied in 105 breast cancer patients receiving four cycles of adjuvant chemotherapy with mitoxantrone + cyclophosphamide (NC chemotherapy). Women accepting the scalp-cooling system were compared for alopecia both against those who refused and against a "reference" group of 109 patients similarly treated but without being offered a scalp-cooling system. Hair loss in the 105 study patients was evaluated by nurses using World Health Organization (WHO) criteria at each cycle of chemotherapy. Concomitantly, tolerance and side-effects of the helmet were also recorded in 48 accepting patients. Similarly to reference group patients, a subsample of 27 accepting patients self-assessed hair loss using a specific questionnaire measuring its frequency and severity and the distress associated with this symptom. Nurses' ratings ( n = 105) indicated that hair loss frequency was constantly lower, at each cycle of chemotherapy, in study patients with scalp-cooling system ( n = 77) than in those without ( n = 28). Differences between the two groups were statistically significant at cycles 1 and 3 ( P < 0.05). When compared with those reported by reference group patients ( n = 109), study patients' self-measures of alopecia frequency ( n = 27) provided even more marked results than those achieved by nurses (cycles 1-3: P < 0.01; cycle 4: P < 0.05). Tolerance was generally good and no scalp metastasis was observed among the 77 accepting patients followed up. This study demonstrates that scalp cooling was an effective method of protection against hair loss caused by NC chemotherapy. Its routine use as part of adjuvant chemotherapy, especially in cancers with low prevalences of scalp metastasis, should be seriously considered.

High-dose steroid pulse therapy for the treatment of severe alopecia areata.

Growing evidence shows alopecia areata (AA) to be a T cell-mediated organ-specific autoimmune disease. This study aimed to evaluate the efficacy of high-dose steroid pulse therapy in Taiwanese patients with severe widespread AA exceeding 40% of the scalp. A total of 17 Taiwanese patients with severe AA lasting less than 2 years were treated once monthly at the outpatient clinic for six sessions. Children younger than 12 years of age received oral prednisolone (5 mg/kg) in three divided doses, while for adults, 500 mg methylprednisolone was infused intravenously over 2 hours. Patients with multifocal AA exhibited the most favorable response, with more than 75% hair regrowth (9/11). Relapse occurred in two patients at 4 and 8 months after the last treatment, respectively. One patient with ophiatic AA showed a transient response, but subsequently lost hair even upon continuation of therapy. Two patients of four with alopecia totalis had full hair regrowth but one lost hair again 6 months later. In the only patient with alopecia universalis, less than 10% hair regrowth occurred. No major side effects were observed. In summary, 11 of 17 patients (64.7%) had more than 75% hair regrowth after steroid pulse therapy. Our results indicated that steroid pulse therapy, given at 5-10 mg/kg once monthly for an average of 6 months, is effective and well tolerated in Taiwanese patients with severe multifocal AA lasting less than 2 years.

Prevention of temporal alopecia following rhytidectomy: the prophylactic use of minoxidil. A study of 60 patients.

BACKGROUND: Temporal hair loss that results from traumatized hair follicles following rhytidectomy is an unsightly complication that can distress both the patient and the operating surgeon. Topical minoxidil is a proven therapy for androgenic alopecia and female senile alopecia. It has also been found to be useful in preventing the hair loss that commonly follows hair transplantation. OBJECTIVE: To analyze through a retrospective study the effect of topical minoxidil on the incidence of temporal hair loss following facelift procedures. To our knowledge this is the first study to investigate the role of minoxidil in preventing post-rhytidectomy temporal alopecia. METHODS: The charts of 60 women with a mean age of 58 years who underwent primary cervicofacial rhytidectomy were studied. Either a standard SMAS/flap technique or pliation was done in all cases. Each patient received either 2% or 5% topical minoxidil for 2 weeks before surgery and for 4 weeks after surgery, with a 5-day break period beginning on the day of surgery. Patients were monitored for complications immediately postoperatively and in 3-6 months of follow-up. RESULTS: Almost 80% of the patients underwent SMAS/flap procedures. Transient temporal alopecia was noted in only one patient, 6 weeks after discontinuing minoxidil. This resolved within 4 weeks of its reintroduction. The only other complications noted included minor hematomas (3.3%), skin slough/infection (1.7%), minor transient and localized edema (8.3%), minor ecchymosis (1.7%), a unilateral neuropraxia of the buccal nerve lasting 3 months (1.7%), and a minor temporary unilateral skin depression (1.7%). Side effects of minoxidil were not observed. CONCLUSION: On comparing our findings to results of larger rhytidectomy series in which minoxidil was not used prophylactically, and our experience before using minoxidil, we conclude that minoxidil plays a role in effectively preventing the temporal hair loss that occurs following primary cervicofacial rhytidectomies. We also found that minoxidil did not negatively impact on the risk of hematoma formation, skin necrosis, edema, or ecchymosis. Side effects of minoxidil did not present a problem.

Effectiveness of the MSC cold cap system in the prevention of chemotherapy-induced alopecia.

OBJECTIVE: To study the effectiveness of the MSC cold cap system to prevent chemotherapy-induced alopecia. METHODS: The system was applied in 83 cancer patients (mean age 49.8 years) undergoing chemotherapy with alopecia-causing agents. Seven patients did not tolerate the system. Seventy-six patients were evaluable for assessment; 26 received anthracycline (group A), 33 taxane (group T), 5 anthracycline plus taxane (group AT), 7 intravenous etoposide (group E) and 5 ifosfamide with or without other alopecia-causing drugs (group I). In group A, 18 patients received conventional (subgroup Ac) and 8 high doses (subgroup Ah). In group T, 8 patients received docetaxel (subgroup D) and 25 paclitaxel (subgroup P). Alopecia grade 0-1 (Dean's system) was considered as treatment success. RESULTS: Grade 0-1 alopecia was achieved in 49/76 (64.5%) patients: group T 23/33 (69.6%), subgroup P 16/25 (64%) and subgroup D 7/8 (87.5%); group A 18/26 (69.2%), subgroup Ac 16/18 (88.8%) and subgroup Ah 2/8 (25%); group AT 1/5 (20%); group E 6/7 (85.7%), and group I 1/5 (20%). CONCLUSIONS: The MSC cold cap system is effective in preventing alopecia from anthracycline, etoposide or taxane but not from anthracycline-taxane combinations or ifosfamide-containing regimens.

Being such a complex biological process, hair growth biology is still a work in progress. Noetheless, several therapeutic methods, including drugs, surgery, and suppelements have been in use to help those who attempt to restore their hair. None of these approaches are perfect due to the diversity in the causes underlying hair loss. Also, most of chemical drugs and hair transplantation surgeries are accompanied by undesirable side effects.

DreamPharm offers Hair Million to address hair loss problems. Numerous anecdotal cases have demonstrated that this herbal formula based on authentic Chinese herbs actually improves the age-related hair thinning and hair loss among a significant fraction of people who take it regularly. We still do not understand the mechanisms of action as to how Hair Million works to stop hair loss and promote hair growth, despite all the positive anecdotal observations. Neither scientific research nor placebo controlled clinical analysis has been conducted because it will cost dearly. Lack of scientific/clinical research is quite common in herbal arena. Just because science hasn't scrutinized we should not stop taking daily food and herbal supplements altogether: our life must go on until we have better understandings of food and herb. There are two merits in this hair restoration herbal formula: Firstly, Hair Million is relatively inexpensive, and secondly, it is made of edible herbs that are known to be safe when consumed in regular quantities.
