Minoxidil’s success rate for effective change is about 60% for some type of result.

I still have a full crown hair wise but you can clearly see the skin, the hairs are transparent, they have basically no pigmentation and that’s why it looks very thinning. What is the underlying science behind loss of pigmentation in AA? I couldn’t find any studies on the web

Miniaturized hairs often lose pigment and color because the hair follicle production is impaired and continues to get worse as the process progresses. As the hairs get thinner and thinner, they contain less pigment and eventually become clear (see-through) as the pigment cells in these hairs die. These hairs also often stop growing before eventually falling out completely.

I ‘ve been taking propecia for the past 4 years but now I really wish to donate blood at least once in my lifetime.
As you know Finasteride users are not allowed to donate blood. According to one of your previous posts Finasteride is cleared from the blood stream within 48 hours.

So I planned to stop taking propecia for a week, donate blood and resume taking the pill. A week seemed a reasonable
amount of time also because according to the information I found on the internet, DHT levels take a whole week to be
back to normal once you stop taking it.

Unfortunately, however both on the Red Cross site and other sites, they state you need to wait at least 30 days after
the last dose of Finasteride.

Why do I need to stop for a whole month if Finasteride is cleared from my blood stream within a few days? Wouldn’t say,
two weeks be safe enough?

You need to wait a month because that is the policy of the Red Cross. Two weeks may be “safe” but you have to follow the organization’s policy.

Dear Doc,
I have been experiencing hairloss for the past 8 months. I still have a good amount of hair it’s just become alot thinner. My problem is that on my right side about 4cm above my ear I have a patch that has gone extremely thin. It’s not bald but it looks as if someone has got a pair of clippers and shaved a chunk of my hair hair off – it looks rather odd. The other side is fine. Why do think this has happened? Thanks.

Some people have a different genetic trait in the area above the ears. It is usually on both sides and frequently present for a long time. There are a variety of hair conditions that can cause patchy hair loss or thinning. You need to see a good dermatologist for an examination and an opinion. You should also get your hair mapped out for miniaturization to see if this is happening in other parts of your scalp.

Eye lashes are 1/3rd as long as eyes are wide. This is true, not only for most humans of all races, but for 21 other mammal species as well. This is the body’s spectacular engineering to control the air flow around the eye to keep dust out and moisture in, reports Dr. David Hu of the Georgia Institute of Technology this year (Journal of the Royal Society interface). He was able to determine this by computer modeling the air flow around the eye as lash length changed. “By reducing airflow over the corneas, eyelashes create a boundary layer of slow-moving air around the eye”, reports The Economist, February 28, 2015.

The fact that eyelashes are used in flirting, may be an acquired feature of the human species. I apologize to our female readership if I burst their styling and flirtatious bubble.

Why do MDs suggest taking finasteride post transplant to keep the hairs? Just for keeping the non-transplanted hairs from falling out and having lower density? Nothing to do with the new hairs, right?

Finasteride after a hair transplant prevents the miniaturized hairs from falling out permanently. This is particularly important in men under 30 when their hair loss is most active.The new hairs in the recipient area do not need the finasteride to grow, just a good surgical team.
