(Reuters) – A large study adds to evidence that people with type O or Rh negative blood may be at slightly lower risk from the new coronavirus.  Among 225,556 Canadians who were tested for the virus, the risk for a COVID-19 diagnosis was 12% lower and the risk for severe COVID-19 or death was 13% lower in people with blood group O versus those with A, AB, or B, researchers reported in Annals of Internal Medicine. People in any blood group who were Rh-negative were also somewhat protected, especially if they had O-negative blood. People with type O blood, and those who are Rh negative, may have developed antibodies that can recognize some aspect of the new coronavirus and therefore might partly protect them against it, coauthor Dr. Joel Ray of St. Michael’s Hospital in Toronto told Reuters.

“Our next study will specifically look at such antibodies, and whether they explain the protective effect,” Ray said. But whether or how this information might influence COVID-19 prevention or treatment is still unclear.

I know DHT shrinks hairs on male pattern baldness but Does DHT destroy the follicle? And does alopecia areata destroy the follicle or just cause hair to fall out?

Hair that has genetic balding eventually die. It is called Apoptosis of the hair follicles and it is genetically coded to the number of hair cycles a hair may live. Alopecia areats is an autoimmune disease that also has a genetic propensity; however, if it it treated successfully with appropriate anti-inflammatory drugs, it can reverse and sometimes recur.

You either had too few grafts placed or what was placed, much of it didn’t grow. The number one cause of a hair transplant failure is errors on the surgeon or the surgical team. I wrote about it with humor here: https://baldingblog.com/hair-transplants-last-for-your-life-make-sure-you-can-live-with-them/

Someone sent me this picture while sitting on a bus. He thought is was interesting enough to send it on. I hope it brings a smile to you as it did to me.

How do you know if it is working if I don’t see growth yet?  Should I wait more time before I give up?

You must remember that finasteride often just slows or stops the loss, not reverses the loss, so you may not see much it it slowed or stopped the loss, unless you stop the drug and then you will know that it was working, possibly too late

I got this set of photos from a group of doctors who share information with each other. It shows an FUE that was performed with a large punch. I wouldn’t call it an FUE as it gives the reference to FUE a bad smell.  These grafts contain 5-7 hairs each, typical of the use of a large punch.  It is hard to imagine that this still happens today. This problem is easily repaired by most reasonably skilled surgeons who understand how FUE is done the right way.  His donor area is another issue that needs to be addressed as well, but not so simply.

Well, if it does the job… from tressless

This actually works, but not with a gloss paint. There are spray products out there that work to thicken up the hair behind the hairline, on the top and crown of the head. These products are called Concealers.

Would any loss suffered from a hair system just grow back once you stop using the hair system?

Hair systems produce traction alopecia so the longer you use them the more permanent the hair loss becomes.

I’m 30 years old and at the end of my rope. I first got on fin in 2016 after noticing thinning in my crown. Around early 2019, shortly after I turned 29 and started a stressful job, fin stopped working for me. Within four months, I lost an inch off my hairline and almost half the density of my front third of my scalp. I got on 0.5 mg dutasteride every day around April 2019. Dut seemed to stop the loss until now, when I started diffuse thinning again on my front and — for the first time in years— my crown. 12 months after starting dut, I am significantly below baseline, with signs of diffuse thinning all over the top of my scalp.

Dutasteride (blocks 85% of 5 alpha reductase) is not the magic bullet for hair loss. It is just a little more effective than finasteride (blocks 70% of the 5 alpha reductase). See this post: https://baldingblog.com/realize-fin-isnt-working/ which also applies to dutasteride.

Does finasteride work for diffuse thinning on the top of the head as well as the upper corners of my forehead hairline thinning? Additionally, the thinned hair that remains on top of the head is fine hair. Do I have any chance of this working for me?

Once can never predict who and where finasteride will work. Experience shows it helps when hair is miniaturized and when the hair loss is more recent (generally speaking). Great results are not often seen in the frontal hairline, however with miniaturization present with recent hair loss, it may work better than with complete recession and no miniaturized hairs present in the hairline.

I used Minox for 9 Months now, didn’t see much of difference in my diffuse hairloss as I always cut it short. However 4 months ago, I started taking Finasteride 1mg, microneedling 1.5mm every week or 2 weeks. I saw huge improvement in my hair in the last 4 months (Pictures of improvement after 4 months Microneedling+ finasteride are attached to the mail). I used a german brand Finasteride called “Finaristo”. Now since a month I switched to another generic Finasteride 1mg from “Relonchem” shipped from a registered NHS UK pharmacy, because it’s much cheaper than here in Germany. I am now shedding like crazy and this is the first time I notice a shedding in my whole treatment regimen. would you recommend me rebuying the expensive generic german brand so I don’t lose my results? or is it a normal shed at 4th month of finasteride that should go away? And if goes away, how long until it does?

Maybe the new medication is not what you are thinking you are buying and if it is a counterfeit, then that would explain the shed

The scalp has a very high blood flow when there is a full head of hair. As hair is lost from genetic balding, the body reduces the blood supply to the scalp (not the other way around). I had a patient who stood on his head 2 hours/day for a year to bring more blood to his scalp, he still became bald until I transplanted him. With the new hair, the blood supply to the scalp increased.

There is too much crusting present making it easy to lose grafts.  I make it a point to get all of the crusts off on the day of the surgery as well as the day after the surgery to avoid this problem. Our article shows when grafts can be lost safely: https://newhair.com/wp-content/uploads/2018/11/mp-2006-graft-anchoring.pdf. Here is a video that shows how to wash your hair:  https://baldingblog.com/what-is-the-washing-technique-that-you-use-for-after-a-hair-transplant/

Read this article and then you will understand what is happening to you and the timing issue.  You should go back and see your surgeon.

Tenting as shown in the photo below, reflects the skin of the graft that was transplanted at the time of the surgery. Good trimming of the grafts by the surgical team avoids this. If you have this, it tells the viewer that you had a hair transplant something that no one wants to happen.
