Hair follicles are genetically programmed from birth. It is the genetic coding that determines the behaviour of the hair follicles through life. Whether a hair transplant will grow forever will depend on the genetic condition of the hair follicles used.
Hair loss causes an interruption in the normal phases of hair growth. This results in either temporary or permanent hair loss. Besides the most common hair loss, other causes can be by hormonal problems, disease, medication, medical treatments, heredity, infection and nutritional deficiency.
Genetic Hair Loss
Male Pattern Baldness (MPB) in men and Female Pattern Baldness (FPB) in women. The hair loss gene is passed down genetically through the family members. Either maternally or paternally sides can carry the gene. Male Pattern Baldness in severe cases can manifest in advanced hair loss. The female baldness pattern, although can in some cases mimic the male patter. That said, more normally takes the form of diffused loss behind the hairline and over the top of the scalp.
Male and female Hair Loss Stages
Hair loss stages are categorised in useful guides to help diagnose. They scale the extent of the hair loss, for both men and women. The Norwood Scale is a classification of MPB for men. From remedial thinning to progressive hair loss. The Scale starts at 1 at its most minor up to 7 as the most aggressive form of hair loss. The female version is known as The Ludwig Scale. This works in a very similar way to categorise a stage of
Where Is the Genetically Strong Hair Located ?
Traditionally scalp hair has been the donor source for a hair transplant. This hair is around the sides and back of the person´s head. Genetic hair loss leaves a band of hair in this area even with advanced hair loss stages. This hair does not carry the baldness gene and immune from male or female pattern hair loss. Other hair loss conditions can still affect the hair growth in this area though. There is no definitive safe zone to remove hair from. There is no demarcation lines between strong and weak hair. The strong hair needs to be isolated from the weaker hair. How this is performed depends on the hair transplant technique used As a result, the hair extraction method differs depending on the technique.
Safe Harvesting – Educated Extraction Pattern
The safe strip zone will be measured, length and width. The hair in this area is then shaved for ease in harvesting. This also allows to correctly check the follicular unit density. As well as calculate any miniaturised hair in the safe zone. The strip area with Follicular Unit Transplant is positioned along the occipital bone. Even with advanced hair loss stages, this will remain within a safe zone. FUE has a wider safe zone to harvest FU from. Although, this does not mean more hair can safely be removed with Follicular Unit Extraction.
Assessing the FUE donor it is possible to see the hair quality contrasts between areas. For example, higher % of hair miniaturisation around the areas of genetically weaker hair. This can occur at the nape of the neck, and around the ears. Also, the area when genetically strong hair meets weak hair. But this is not always obvious when treating minor hair loss stages. If the hair is not DHT immune and it is used the hair will fall out at a later date. When mapping out the FUE donor zone a safe area needs to be left untouched between the strong and weak hairs.
Don´t Take More Than Is Safe
Sometimes the heart rules the head. Wanting to believe something is possible when logic tells you it is not. The result can be to look back a regret being so aggressive. Your
