The Value of Double vs Single Follicular Unit Technique

I have seen on the internet, the promotion of a double FU technique. Can you explain it to me and tell me about the value of a double follicular unit technique.

Follicular units (FUs) have one, two, three or four hairs each. When they are placed in the recipient area, they are graded in the frontal hairline (FUs with one hair each up front). There are times when the doctor wants to have more two or three hair grafts and the donor area yielded too many one hair grafts (common in Asian patients). In this situation, two single hair grafts (or one single and one double hair graft) are placed into a single recipient site and that is what is referred to as a ‘double FU technique’.

A bald man may get between 250-500 single haired FUs at the leading edge to create a soft, transitional hairline zone. All other FUs should contain more than one hair each to produce value. As each person has a different distribution of single hair FUs out of a harvested strip, the number of single hair FUs are determined by the anatomy of the patient (not the surgeon). So to get more than a single hair FU to place behind the leading edge transition zone, one might have to double up the single hair FUs to get reasonable bulk. More bulk can be obtained by putting a single hair FU with a two-hair FU to create a three-hair FU so that there is a way for the surgeon to determine and control the bulk of the hair that is transplanted.

Dr. Rassman’s Comment: I want to call your attention to the chart below, which discusses sexual side-effects between these medications and the placebo. To find out the real incidence of the Libido and Erectile Dysfunction problems from this study, you must subtract the placebo numbers. If this is true, the incidence is relatively low.

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement, lead to unreliable or uninterpretable data.

 

 

Thickness of Transplanted Hair

Why is the hair from the second transplant just one year ago finer than the hair from my first hair transplant 18 years ago?

The new hair compared to your transplanted hair from 18 years ago should be the same as the hair in the back of your head. Check each area with a micrometer and see if they match.

Gray Hair, Changing Diameter?

When hair turns gray, does the diameter change?

From my clinical experience I can tell you that the gray grafts appear thicker than the non-gray grafts. This is evident in the single hair grafts. Now that you sent me this question, I should measure the gray hair diameter and compare it with the non-gray hair diameter over the next few weeks and maybe get back to you with a small research study. Thanks for the great question!

I think that I was taken to the cleaners by this doctor? (photo)

He did 1500 grafts in just 40 minutes. I counted only 700 or so. What do you think?

The surgeon must make a surgical record of the actual graft count. Ask for that surgical record, as you are entitled to it. In 40 minutes for 1500 grafts, I would say that is ‘god’s speed’. Was the surgeon some deity? The wounds look larger than I would make them. I would need more information about the surgery such as strip or FUE? If it were a strip, the dissection would not have been very careful and in 40 minutes, I believe you may have been, as you said, ‘taken to the cleaners’.

Growing Hair from Body Fluid Injections to the Scalp?

I heard of a technique where your own bodily fluid is injected into the male pattern balding spot and is supposed to grow hair. Can you tell me what you know about this treatment? Is it for real, is it permanent, is it for the frontal part of the scalp etc.?

I don’t know of injecting body fluid (???) in your scalp to grow hair… but I do know some clinics offer platelet rich plasma (PRP) into the scalp in hopes it will provide faster healing after a hair transplant. Some dentists use it for faster healing after a dental procedure. I asked a few dentist friends, one of which is a professor at UCSF, and she believes PRP is controversial even in the dental field.

In the end, this method has never really been proven to grow hair on a bald scalp. If anyone can find a well controlled study for hair growth from PRP, please let me know. Some doctors charge hundreds or thousands of dollars for PRP, but I remain a bit skeptical. The patients we’ve viewed in the office haven’t had the results their doctors promised.

3000 FUE grafts 1 week with ago with cracks on my head, why? (photo)

What you are seeing is terrible post-operative care which has allowed thick crusts to form on your head and then crack. An FUE is treated just like a regular hair transplant with regard to the recipient area while the donor area has open wounds which require daily washing with soap and water. Within 3 days of surgery, you can resume full activities, heavy exercises if you wish.

The recipient area requires daily washes as well to keep the recipient area free of crusts. I generally recommend the use of a sponge and supply my patient with a surgical sponge to fill with soapy water and press on the recipient area daily. By repeating this daily, all crusts can be washed off without any fear of losing grafts. IF any crust are present, use a Q-Tip and dip it into soapy water and roll it on the crusts. That will lift them off without dislodging them but never rub them, just roll the Q-Tip on the recipient crust. I like to see no evidence of any crusting in the recipient area and the crusts from the donor area are gone in 7-10 days with daily washing.

I don’t like the idea of anyone removing grafts that have scabs on them. We have published a paper in a formal medical journal (https://newhair.com/wp-content/uploads/2018/11/mp-2006-graft-anchoring.pdf) that states when a person pulls off a scab (crust) from a recipient area in less than 12 days, the risk of losing the graft is very high. Put a shampoo on your head and let it sit for 10-15 minutes, then gently work the crusts with your fingers. This will take days to get the crust off but you will not disturb the grafts.

I am also disturbed that 3000 grafts were placed in the frontal 3 inch zone of your scalp. Keep in mind that most people have only a bout 7000 grafts in their donor area and if your original donor density was low, then that number could be 4000 or even less. IF your hair is fine, things get even worse. You can contact me for more details on how to evaluate your long term planning if you wish.

Three months on finasteride, minoxidil and microneedling (from Reddit)

Nice early results. It shows the impact of finasteride and minoxidil used in combination. The impact on the crown is clearly better than on the front, but both are better. It is unusual to see results in just 3 months but because he kept his hair short, the new hair impacted by the finasteride and the minoxidil showed better. If his hair was longer, then he may not have seen the value as quickly because only the hair close to the scalp was helped by the finasteride and the minoxidil.

My Hair Was Burned With a Relaxer and It Falls Out and Grows Back Every 3 Years

I had my hair relaxed 9yrs ago and got a burn in the balding area. the burn healed but hair from that area started thinning. 3 yrs later it fell off then grew back again, thinner and on a larger area. 3yrs later same thing happened again. Last yr was another 3yrs later when it fell off again. i haven’t used hair relaxer on my head since 9yrs ago.my scalp hurts a lot on that area.what can i use to restore my scalp and get my hair back. Please please help

You seem to describe a cycle of 3 years where your hair thins and grows back. I have never heard about such cycle and I am not sure how it relates to the chemical relaxer from 9 years ago. Our hair does grow and fall out in cycles but it is not very predictable nor synchronous. Human scalp hair is constantly growing and falling asynchronously. We can lose 100-200 hairs a day but there are 100-200 new hairs growing elsewhere on the scalp at the same time. So this cycle should not be readily perceptible. On occasion some experience telogen effluvium where there is significant hair loss without any inciting cause. There is no treatment for telogen effluvium other than time, as hairs do grow back within a year.

Pain on your scalp is not normal and you should have it checked by your dermatologist.
