Hair Growth Phases Normal hair growth happens in a cycle of 3 oddly named phases: Anagen, Catagen and Telogen. Every single hair goes through these phases, each relating to different states of activity. Read on to find out what on earth they mean.

This open-ended study has demonstrated the hair regrowth response of 148 men who have been treated with an all natural compound solution applied topically to balding or thinning regions of the scalp. The treatment program included regular scalp cleansing with a natural extract scalp cleanser and application of at least 5-10 ml of the all natural compound solution at least twice daily. The data showed that hair counts increased significantly for approximately 85% of the participants in the five month period.

After seven months of treatment, 44% of the patients using the essential oils showed significant improvement in hair growth. The group using carrier oils showed just 15% improvement. In addition, the aromatherapy caused no significant side effects. Researchers concluded that not only did the aromatherapy work, it was ... far safer than traditional alopecia treatments including conventional steroids.
There is no doubt that sex hormones play an important role in the growth, distribution, and pigmentation of human hair. During puberty, secondary hair develops in the pubic and axillary regions. In males, the beard starts to grow and, on a smaller scale, terminal hairs appear on the trunk and limbs. With various endocrinopathies associated with overproduction of androgens, hypertrichosis is a significant feature. The different effects of circulating androgens on various groups of human hairs in various locations lead to the hypothesis that differences exist in the metabolism of hormones in follicular tissue.

The catagen phase is a short transition stage that occurs at the end of the anagen phase.[4] It signals the end of the active growth of a hair. This phase lasts for about 2-3 weeks while a club hair is formed.
Drugs may increase growth of androgen-dependent hairs (hirsutism) or of all hair (hypertrichosis). Hirsutism can be caused by testosterone, danazol, ACTH, metyrapone, anabolic steroids, glucocorticoids and some antiepileptics - phenytoin and carbamazepine.[47] Hypertrichosis can be produced by cyclosporine, minoxidil and diazoxide. Minoxidil and diazoxide open potassium channels in cell membranes leading to hyperpolarisation. The opening of potassium channels could be main mechanism of their hypertrihotic action. Furthermore, it has been shown that other drugs which open potassium channels (P-1075, cromakalim) are able to produce hypertrihosis.[48]
