The human scalp has an average of 110,000 hairs on a global surface of 600cm2, which are growing and falling on a daily basis. On average 50-100 scalp hairs are lost each day. When the balance between the growing hairs and the falling ones is altered, then hair loss starts and baldness occurs.

Hair loss (also called alopecia) can happen at any age, all around the world, mainly targeting men. It is a known fact that 40% of the men will have noticeable hair loss by age 35, this number reaches 65% by 60 years of age. Women are also deeply impacted by such process: 50 to 75% of them suffer noticeable hair loss by age 65. Hair loss can be devastating for one’s self image and emotional well-being. 

According to the International Society of Hair Restoration Surgery, almost 1 million patients worldwide were treated by surgical and non-surgical hair restoration means in 2012. Ninety three percent (93%) of the hair restoration surgery procedures achieved in 2012 were targeting scalp, and 4.5% eyebrows. 

Men represent 86% of the patients for hair transplant surgery and 67% for non-surgical hair restoration. They initiate such treatment at the average age of 38. Each hair surgery enables the transition of 2016 grafts, each containing 4 hairs, representing about 8,100 hairs transplanted on patients’ scalp. Patients generally need 3 procedures to restore the appropriate hair density. Data shows that 64% of the patients’ post-surgery complaints are about the final density of their hair.
