There is no clear association between low serum ferritin and chronic diffuse telogen hair loss.

BACKGROUND: Low iron stores are considered a possible cause of chronic diffuse telogen hair loss in women. Estimation of serum ferritin is recommended as part of the initial assessment when women present with chronic diffuse telogen hair loss, and iron supplementation therapy is commonly recommended for those found to have low iron stores. OBJECTIVES: To evaluate the relationship between low serum ferritin ( 20 micro g L-1. Cessation or reversal of hair loss was not seen in any of these women. CONCLUSIONS: No direct relationship between low serum ferritin and hair loss can be established. The usefulness of serum ferritin in the routine investigation of women with chronic diffuse telogen hair loss is unclear, as is the role of iron supplementation therapy in the management of hair loss.

Does the recipient site influence the hair growth characteristics in hair transplantation?

BACKGROUND: Recently hair transplantation has been widely applied not only to correct androgenetic alopecia, but also to correct hair loss on other parts of the body such as the eyebrows and pubic area. It is believed that the transplanted hairs will maintain their integrity and characteristics after transplantation to new nonscalp sites. OBJECTIVE: To evaluate whether the transplanted hairs maintain their hair growth characteristics after transplantation to a new anatomic site other than the scalp. METHODS: Three study designs were used. Study I: Hair transplantation from the author's occipital scalp to his lower leg was performed and clinical evaluations were made at both 6 months and at 3 years after the transplantation. Study II: After finding changes in hair growth characteristics, transplanted hairs were harvested from the leg and retransplanted to the left side of the nape of the neck (group A). As a control study, occipital hairs were transplanted to the opposite side (group B). Observations were made at 6 months after the operation. Study III: An observational study was done in 12 patients with androgenetic alopecia about 1 year after transplantation of occipital hair to frontal scalp. At each step, survival rates were documented and the rate of growth and the diameter of the shafts were measured for both recipient and donor sites. RESULTS: Study I: Surviving hairs on the lower leg showed a lower growth rate (8.2 +/- 0.9 mm/month), but the same diameter (0.086 +/- 0.018 mm) compared with occipital hairs (16.0 +/- 1.1 mm/month, 0.088 +/- 0.016 mm). The survival rate 3 years after transplantation was 60.2%. Study II: There was no significant difference in the growth rate, shaft diameter, and survival rate between retransplanted hairs (group A) and controls (group B). Groups A and B showed a lower growth rate, but the same diameter, compared with occipital hairs. Study III: There was no significant difference in the growth rate and shaft diameter between the transplanted hairs on the frontal scalp and the occipital hairs. CONCLUSION: These results strongly suggest that the recipient site affects some characteristics of transplanted hairs, such as their growth and survival rates.

Hair loss: an overview.

Hair loss is a common problem in men and women. Correct diagnosis of hair disorders is complex and requires evaluation of clinical presentation, history, physical examination, and laboratory tests. Hair loss may be categorized as hair shaft abnormalities, permanent alopecia, or nonpermanent alopecia. Nonpermanent alopecia, the most common type, includes androgenetic alopecia, telogen effluvium, alopecia areata, and traction alopecia. The hallmark of this group is the possibility of complete regrowth with adequate treatment.

Genetic analysis of the interleukin-1 receptor antagonist and its homologue IL-1L1 in alopecia areata: strong severity association and possible gene interaction.

Alopecia areata is an inflammatory hair loss disease with a major genetic component. The presence of focal inflammatory lesions with perifollicular T-cell infiltrates reflects the importance of local cytokine production in the pathogenesis. In addition to its fundamental pro-inflammatory role, the interleukin-1 (IL-1) system has major effects on hair growth regulation in vitro, with the inhibitory actions of IL-1alpha and IL-1beta being opposed by the receptor antagonist IL-1ra. The novel interleukin-1 like molecule 1 (IL-1L1) which has greatest gene sequence homology with IL1RN, the gene encoding IL-1ra, is another potential IL-1 antagonist. In view of previous studies suggesting a significant role for IL1RN polymorphisms in the pathogenesis of autoimmune/inflammatory disease, we have analysed polymorphisms of IL-1ra (IL1RN+2018) and its homologue IL-1L1 (IL1L1+4734) in a case-control association study on 165 patients and a large number of matched controls. Homozygosity for the rare allele of IL1RN (IL1RN*2) was significantly associated with alopecia areata [odds ratio (OR) = 1.89, 95% CI (1.09, 3.28); P = 0.02], confirming our previous findings of significant association with the IL1RN variable number tandem repeat (VNTR). The results also revealed a novel association involving a polymorphism of the interleukin-1 receptor antagonist homologue IL1L1 at position + 4734, IL1RN+2018, and alopecia areata. The effect of a genotype combining three copies of the rare alleles at the IL1RN and IL1L1 loci conferred a more than additive increase in the risk of disease compared to IL1RN+2018 or IL1L1+4734 alone [OR 3.37 (1.60, 7.06); P = 0.002], suggesting possible synergy between the IL1RN and IL1L1 genes. This effect was stronger in patients with severe disease (alopecia totalis/universalis) [OR 4.62 (1.87, 11.40), P = 0.0022], and in those with early age at onset (< 20 years) [OR = 6.38 (2.64, 15.42), P = 0.0002]. Our results suggest that these polymorphisms within IL1RN and IL1L1 themselves or a gene in linkage disequilibrium with IL1RN and IL1L1 predispose to the more severe forms of alopecia areata.

Since hair growth is a complicated biological process, modern science has yet to grasp a complete picture. A number of traditional and alternative therapeutic methods that include drugs, surgery, and suppelements have been developed to help those who are losing hair. Unfortunately, none of these approaches are perfect for all hair loss problems due to the complexity of the phenomenon and diverse nature of the causes underlying hair loss. Also, most of chemical drugs and hair transplantation surgeries are accompanied by undesirable side effects.

DreamPharm offers Hair Million (have you heard?) to help treat hair loss problems. Numerous anecdotal cases have demonstrated that this herbal formula based on traditional Chinese herbs actually improves hair thinning and hair loss, a condition often associated with aging, for a significant fraction of people who take the formula regularly. It is not yet understood how Hair Million can stop hair loss and promote hair growth. No scientific research or placebo controlled clinical analysis has been performed on these herbs. Lack of scientific/clinical research is not uncommon in herbal arena. Nonetheless, 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. Buy Propecia Online is a clinically tested prescription medication.
