**1. Introduction**

In recent years, hair loss has progressively increased because of the use of various chemical agents, environmental conditions, drugs, and inorganic foods [1, 2]. Androgenetic alopecia affects nearly half of the women and men around the world [3–5]. Hair loss at an early age can be quite traumatic, particularly among young men and women. Baldness can be also problematic in advanced ages, even over 50 years of age. Although there are many causes of hair loss, the most common is androgenetic alopecia.

Hair transplantation is also successfully applied for the treatment of many types of hair losses other than the androgenetic alopecia. The hair transplant can be used in cases such as various cicatricial alopecias, alopecia areata, congenital alopecias, postburn sequelae and to camouflage various skin marks [6, 7]. Both inherent and acquired losses of the beard, mustache, and eyebrow can also be successfully treated with hair transplantation [6, 7]. As hair loss has progressively become a great problem in all populations, patients truly desire to regain their hair and therefore, they may be abused by individuals who are not physicians and who use paramedical methods, particularly topical and herbal treatments.
