Maturation of scalp hair line

Wednesday, March 5th, 2008

I saw an 18 year old patient today who was worried about the recession of his hairline. We mapped his scalp hair to analyze the degree of miniaturization using a digital microscope. Here are pictures from the microscopic of his donor hair (left) vs. very frontal hairline (right).

You can see significant miniaturization in the frontal area. When we examined a few centimeters behind his frontal hairline the miniaturization rate dropped sharply to less than 20% which was consistent throughout the top and crown area of the scalp. The patient’s father lost his hair at an early age. Patient started taking finasteride a month before his visit with us and topical Rogaine about a week before this visit.

What we observed was the maturation of his hair line, which occurs between the ages of 16-25 in most men. Hair line maturation is when the hair line migrates 1 to 2 cm higher than its normal position as when we are child (kiddy hairline). It is more significant in the corners but could be seen in the midline too. As Caucasian men go through the maturation process, the hairline rises, but many non-Caucasian men never experience hair line maturation and the hairline stays flat and low.

The best way to distinguish the maturation of the hairline from the early stages of baldness is by comparing miniaturization in different scalp areas. If you are experiencing early hair loss, your miniaturization could be seen behind the first centimeter of the frontal hairline, but if the rate of miniaturization drops sharply it could indicate that the hair line is going through maturation and the hair loss may stop shortly after maturation is complete.

We stopped all anti hair loss medications that the patient recently started, and we recommended another miniaturization study in 6 months to a year to follow his hair loss progression.

Scalp Hair Miniaturization

Wednesday, February 27th, 2008

Miniaturization of scalp hair is a part of the hair loss process in which hair becomes finer over time before falling out. Microscopic evaluation of the scalp and hair can help determine the rate of miniaturization on human hair. Balding in men and women usually is not obvious until significant miniaturization is present.

Scalp miniaturization mapping is necessary for most hair loss patients to predict their future hair loss.

The appearance of baldness is not obvious until more than 70% of hair is miniaturized in most people. A miniaturization study should be part of the hair loss evaluation of a patient and could be used as predictor of future balding in a given area. Significant hair miniaturization is seen in patients who are in the active phase of hair loss and this evaluation could determine a patients’ response to a certain type of medical treatment.

Here at US Hair Restoration, we map the patient’s scalp with miniaturization study as part of initial hair loss evaluation before starting any medical treatment or performing hair transplant surgery. Young patients with significant miniaturization are prone to losing their vulnerable hair after a hair transplant surgery due to the stress of surgery on skin and hair follicles. This phenomenon is called shock loss and occurs less in patients with minimal amounts of hair miniaturization.

We consistently track our patients through miniaturization studies when they are on a treatment plan to gauge hair gain or loss. This way we can objectively evaluate the effectiveness of our treatment.If you are balding and are willing to do something about it either by hair transplant surgery or medical treatment, you should have your hair mapped for miniaturization to have a baseline assessment of current hair loss status. This way we can assess the effectiveness of medications and predict in which areas you will have the most hair loss. This can help your hair transplant surgeon cover areas or future hair loss so that you are not obliged to take on multiple surgeries to chase the balding hair.

Having 10 to 20% miniaturized hair could be normal and not part of the balding process. Scalp hair goes through two main phases: Growth phage (Anagen) and resting phase (Telogen). The Growth phase in scalp hair of normal people can take between 1 to 6 years, where the resting phase is about 4 to 6 weeks. When we lose one hair to the telogen phase, another hair will grow from its follicle which will be represented by a few tiny hairs showing hair cycling, in the area and not necessarily the balding process.

If we see over 20 percent hair miniaturization in a general area, it is common indication of active hair loss in the area. Higher numbers of miniaturization could represent active hair loss and progress of balding in the future.If you are a balding man with significant miniaturization, you should take finasteride after mapping your scalp. The effect of medical treatment of baldness is very gradual and may take at least six months for any detectable improvement in miniaturization of hair.

Human Growth Hormone and Hair Regrowth?

Friday, February 15th, 2008

Question:
What is the effect of HGH (Human Growth Hormone) injection on hair regrowth?

Answer:

There are some research based articles that support the positive effect of growth hormone on hair loss. Also there are many reports of hair loss after treatment of acromegaly (a disease caused by increased levels of human growth hormone) by different medications such as octreotide. Growth hormone is a medication with multiple target organs. This can explain the wide range of effects seen after HGH use. Growth hormone can affect muscle strength, body fat, exercise tolerance, skin texture and elasticity, would healing, hair growth, sexual potency, memory … and the list goes on and on. However, human growth hormone or HGH like any other hormonal medication has its own side effects and the effect of growth hormone on hair and hair loss does not justify its use for the purpose of treating baldness.
