About Genetic Hair Loss

This blog titled “About Genetic Hair Loss” was written by Scott Moore for Great Directions and PRP for Hair Loss.

Androgenetic Alopecia (also known as hereditary hair loss and genetic hair loss), is the most common form of hair loss/thinning to impact men & women.  As it’s name suggests, androGENETIC alopecia, is a condition that is INHERITED from your parents when you are born.  The hair loss gene can be passed on by either your Mother or Father (or both). 

The hair loss gene causes hair follicles to become weak when they come in contact with a hormone known as DHT.   Only hair follicles through the frontal hair line, midscalp and crown areas of the scalp are damaged by DHT.

What is DHT?

DHT is a hormone that everyone has in their body.  Here are some facts about DHT;

    • DHT stands for Di Hydro Testosterone
    • DHT is formed when a Testosterone Hormone bonds with an enzyme to create DHT
    • The enzyme is called 5 alfa reductaze (5ar)
    • The enzyme is made from a person’s Low-density lipoproteins cholestrol.
    • An increase in LDL cholestrol levels can lead to an increase in the 5ar enzyme and therefore lead to an increase in DHT.
    • An increase in testosterone levels can also lead to an increase in DHT.
    • Only people who have inherited the hair loss gene experience hair loss caused by DHT

How does DHT cause hair loss?

Remember, DHT on its own does NOT cause hair loss.  You need to inherit the hair loss gene from your parents first, the hair loss gene unlocks a genetic weakness in your hair follicles when they come in contact with DHT.  Only follicles in the frontal, midscalp and crown areas of the scalp are impacted by DHT.  However, lets review how DHT damages your hair follicles:

    • DHT minaturises your hair follicles
    • DHT causes your hair follicles to weaken
    • DHT injures your hair follicles extremely slowly
    • As your follicles become smaller, they attract less blood supply
    • This results in the follicles growing weaker and thinner strands of hair
    • As the damage continues, hair becomes thinner, weaker, finer and flatter
    • Eventually hair follicles can die
    • If the hair follicle dies, a strand of hair can not be produced.

Why doesn’t the body try to heal the injured follicles?

DHT damages and injures the hair follicles very slowly, therefore the body does not recognise that there is an injury that needs healing.  With most injuries, the body will send PLATELETS and PLASMA from your blood to the injury to repair the damage.  However, because DHT injures the hair follicles extremely slowly, the body is not able to recognise the injury, and therefore allows the injury and damage to continue.

What is PRP? 

PRP stands for Platelet Rich Plasma.  It is sourced from a person’s own blood supply.  In a normal blood sample, you have:

    • RED Blood Cells – these blood cells carry oxygen
    • WHITE Blood Cells – these blood cells fight disease and infection
    • PLATELETS – these blood cells repair cells that are damaged or injured
    • PLASMA – this is the fluid part of your blood, it carries nutrients through your body.

Where does PRP come from?

PRP or Platelet Rich Plasma is simply a sample of blood, and the platelets and plasma are separated from the other components of your blood.  Therefore increasing the concentration of:

    • PLATELETS – these blood cells repair cells that are damaged or injured
    • PLASMA – this is the fluid part of your blood, it carries nutrients through your body.

In summary, does PRP treat hair loss caused by DHT?

By creating a controlled injury on the scalp (skin) where the hair loss is occuring, this will signal the body to send PLATELETS and PLASMA to the area, to repair the injured cells.  By adding in PRP to the area, we are increasing the amount of repairing cells (platelets) and nutrients (plasma) in the area.  Therefore, the skin cells and the hair follicles are exposed to large amounts of healing platelets and nutrient rich plasma.  PRP does not directly REDUCE DHT levels, it can help to reduce the DAMAGE and INJURY caused by DHT on your hair follicles.  Some patients are able to rely on PRP treatments only, however other patients may require PRP treatments and a DHT medication.  Either way, PRP is able to reduce the injury caused by DHT, and PRP is able to help to regrow thinning hair thicker.

PRP Treatment Timings?

Initially, we recommend 4 x PRP for Hair Loss Treatments – see below:

    • 1st PRP Treatment
    • 2nd PRP Treatment (spaced 1-4 weeks after the 1st treatment)
    • 3rd PRP Treatment (spaced 1-4 weeks after the 2nd treatment)
    • 4th PRP Treatment (spaced 1-4 weeks after the 3rd treatment)

Then, patients have a choice to either:

    • MAINTAIN the results they have achieved so far = 1x PRP Treatment every 2-4 months 
    • ENHANCE and PROMOTE more hair regrowth = 1x PRP Treatment every 1-2 months
