Why is Cell Differentiation the Major Obstacle for Hair Cloning?

December 18th, 2007

Q: What is the major obstacle to hair cloning?

A: Although many problems remain, the main one is to keep cloned cells differentiated (the ability to perform a specialized function, like producing a hair). There are certain cells in the skin, called fibroblasts, which reside around the base of the hair follicle. These cells are readily multiplied in a Petri dish. When these cells are injected into the skin, they have the ability to induce a hair to form (they are differentiated). The problem is that when these cells are multiplied in culture, they tend to lose this ability (they become undifferentiated).

Will Second Hair Transplant Session be Different than First Session?

December 17th, 2007

Q: My first hair transplant was a breeze. Will a second procedure be any different than the first? — B.B., Murray Hill, N.Y.

A: Generally in a second procedure, a patient can expect less swelling post-up although the reason for this is not known.

There will also generally be less shedding in the second hair transplant session since the weak miniaturized hair that will be shed is often lost in the first session and the previously transplanted hair is generally more resistant to shedding.

Do You Use Digital Imaging to Forecast Hair Transplant Results?

November 25th, 2007

Q: Do you use computer type imaging to create the best way to ensure you (or any hair transplant surgeon) have the same goal or target “picture” of the particular patient’s restoration as that particular patient has as his “picture?” –F.D., Laude, Missouri

A: I prefer not to do imaging since it tends to oversell the hair restoration procedure.

In addition, the technology is unable to accurately represent what the hair transplant will really look like as there are many hair characteristics that it can’t take into account.

Seeing lots of actual photos of hair transplant patients is much more instructive – and more honest (if the photos are taken correctly). At the time of the consult I design the hairline and photograph it.

Can Stress Cause Diffuse Unpatterned Hair Loss (DUPA)?

October 30th, 2007

Q: Can stress produce diffuse unpatterned hair loss (DUPA), or was it bound to happen anyway? — D.D., Park Slope, Brooklyn

A: Both DPA (diffuse patterned hair loss) and DUPA (diffuse unpatterned hair loss) are genetic conditions, unrelated to stress and would have happened anyway. These types of hair loss are characterized by a high percentage of mininiaturized hair in broad areas of the scalp. See the Classification of Hair Loss in Men and Classification of Hair Loss in Women pages on the Bernstein Medical – Center for Hair Restoration website for more information on this topic.

In contrast, stress generally presents as increased hair shedding, a reversible condition referred to as telogen effluvium. It is called this because the normal growing hair is shifted to a resting (telogen) phase before it temporarily falls out. Increased miniaturization is not associated with telogen effluvium.

Allergic Reaction to Rogaine Liquid but Not Foam?

October 15th, 2007

Q: Our dermatologist originally suggested our son use the 5% Rogaine and he developed an allergic reaction to it. Allergy tests confirmed it was the propylene glycol causing the reaction. I understand that Rogaine foam has 5% minoxidil in it but no propylene glycol. Is that correct? — B.M., Lower East Side, N.Y.

A: In addition to minoxidil 5%, Rogaine Foam contains: butane, butylated hydroxytoluene, cetyl alcohol, citric acid, fragrance, glycerin, isobutane, lactic acid, polysorbate 60, propane, purified water, SD alcohol 40-B, stearyl alcohol — but no propylene glycol.

After Hair Transplant, What are White Specks on Scalp?

September 26th, 2007

Q: After the day of the procedure, I could see what appeared as white specks on top of my scalp. Some are sticking out above the scalp more than others. I was wondering if the entire follicular unit should be at the level of the scalp. Is it normal for some part of it to be above the scalp? (I did not receive the procedure from you.) — T.C., London, U.K.

A: It is normal for the grafts to be a little elevated and you should expect them to flatten as they heal.

The effect may be exaggerated in the shower as the grafts become hydrated, but they should settle down soon after you dry off.

Can Stress Cause Hair Loss or is that a Myth?

September 6th, 2007

Q: I’ve been dealing with daily mental stress for the past few months. I’ve noticed that during that time, I’ve experienced a lot of frontal hair loss and thinning. I thought stress was a myth for causing hair loss. — R.P., Upper East Side, Manhattan

A: Stress may cause temporary shedding, but it generally does not affect the long-term course of genetic hair loss.

It seems that women’s hair is affected by stress more commonly than men’s hair, but the reason is not clear.

Should Young Person Start with Hair Transplant at Crown?

August 21st, 2007

Q: I am 26 years old, have had two successful hair transplants, but am still losing hair in the crown area. The doctor I have worked with told me that he does not do crown work on anyone until they are at least 40 (due to lack of donor area). I have very thick hair and the transplanted area looks as if nothing was lost. Would you do work on someone my age in their crown area if they have enough donor hair? — A.W., Brooklyn, N.Y.

A: Although I am hesitant to start with the crown when transplanting a younger person, if you have good coverage on the front and top of your scalp from the first two sessions then extending the hair transplant into your crown may be reasonable. It depends upon your remaining donor supply and an assessment of how bald you will become. I would need to examine you.

If it is likely that you will progress only to a Norwood Class 6, then transplanting your crown can be considered. If you will progress to a Class 7 then you should not since, in the long term, hair that was placed in the crown might be better used for other purposes, such as connecting the transplanted top to receding sides.
