Hair Loss Explained


The Number 1 reason for all hair loss in men and women is Androgeneic Alopecia.  It accounts for approximately 95% of hair loss in men .  Women also suffer from hair loss issues and make up about approximately 40% of those suffering from this condition.


In the past 10 years the reasons for hair loss has become more fully understood and Dihydrotestosterone (DHT) has become identified as the main reason.  DHT binds to receptors within the follicles causing shrinkage which inhibits healthy hair growth. 


In many cases it can be treated but you need to understand how hair grows and potential causes hair loss.


Causes of Hair Loss


Men and women are susceptible to inherited genes.  If your parents had thin hair, the likelihood is that you will follow in their footsteps. Female-pattern hair loss is called androgenic or androgenetic alopecia, it is caused by DHT and is basically the female version of male pattern baldness. Men are more likely to lose their hair than women and is this usually caused by male pattern balding.



Stress causes changes in the hormones and can shock the hair follicles into shedding more hair than normal.  However, a key thing to note here is that the stressful event may not cause hair shedding for some months later.



What we eat can impact negatively on our hair.  Lack of protein, lack of vitamin B and too much vitamin A can all have a negative effect on our hair production as reported by the American Academy of Dermatology.



Changes in the levels of female hormones can cause hair loss, so switching birth control pills or coming off the pill may have this effect.  Pregnancy related hair loss tends to occur post partum and some women experience accelerated hair shedding as the hormones resettle. 

Changes in hormones during the menopause can also cause hair thinning.  Again the male hormone receptors become more active as female hormones decline.



There are a raft of illnesses and medications which can negatively impact your hair growth, they include but are not limited to: anemia, thyroid issues, lupus , lichen planus, scalp infections.  The medications that can have a negative effect on hair growth are too numerous to mention but can be caused by medications used to treat: fungi, cancer, depression, auto immune disorders and blood pressure.



Traction Alopecia is on the rise due to the hair being pulled tightly into pigtails, cornrows or hair extensions woven or glued in.  They put too much stress onto the follicles eventually causing the follicle to weaken and die.



Hair pulling (trichotillomania) is when people have a habit or urge to pull their hair out, this may be from the scalp, eyelashes or brows
