Dear Dr. Rassman
For a quite a lot of time I had been looking for information regarding hair diameter and its relation with hair loss (I know hair diameter can be used for diagnosis), my question is if thicker hair producing follicles need more time of exposure to dht to give the appearence of hair loss. In other words is thicker hair a a delayer/protective factor for baldness?

People with coarse hair may not show the reduction of hair shaft thickness that those with fine hair would, but DHT will impact the hair equally (regardless of hair character) once the genetic pattern is expressed.

No, I don’t believe that time of day you take the drug has anything to do with its effectiveness because the drug really works by its fixation on the hair follicle which holds for at least one week or more.

You mentioned in one of your posts that you generally use grey/black or grey/brown ink tones. I understand that they will fade over time but does the fading change the remaining pigment to a slight blue tone. This is the type of thing you see with tattoos that use black ink which generally fade to a blue tone over time. Or does the ink hold its colour integrity over time? Thanks

All pigments deposited under the skin will turn blue/ green over time. The time frame that this happens is within a week to a month (not years). And the blue I am referring to is nothing like the blue in this post, it is a black color with a tinge of blue to it.

Any claim that it does not is a marketing gimmick as the human body will react with the pigment as well as the layer of overlying skin will alter the perception of color. For example your red blood vessels will look green under your skin but the green you see is an absorption issue because these blood vessels contain red blood, yet these blood vessels don’t look red under the skin. There is actually a paper written on this topic HERE.

The green /blue that some may think of (or you may be referring to) are the old pigments or cheap brands that oxidize and actually change color dramatically. The green/ blue I’m referring to is generally not noticeable unless you have a keen sense of color. If the SMP pigment is high quality and the person applying them is experienced you should not have this issue. The best and ultimate test is to physically see a SMP patient up close in person. Don’t rely on advertisements or photos.

I have prescribed it for a number of family members. It is a cooling head system that keeps the blood circulation to the scalp low during chemotherapy. On the three family member I recommended using it, none of them lost all of their hair although there was some thinning on one woman with Breast Cancer Chemo, but unlike many of her friends, she kept almost all of her hair for the entire chemotherapy period. (see: https://baldingblog.com/cold-cap-is-now-fda-cleared-to-hold-on-to-ones-hair-during-chemotherapy/ and see other links: https://baldingblog.com/?s=cold+cap ). Psychologically it is a Godsend for women with breast cancer not to be reminded of their disease every time they look in the mirror and see a bald woman.

I was curious if you believe in testosterone itself causing hair loss and this being raised by finasteride and dutasteride can worse things for some people? I got diagnosed with a folate deficiency, but addressing it the past two months doesn’t seem to have helped, so I’m wondering if this could be the case.

Exogenous testosterone can cause hair loss in men with the genes for hair loss and as testosterone goes up, so does the amount of DHT found in your body

Everything taken under the tongue goes in faster, but there is no point to it as it is tissue fixation at the hair level that is important, not the blood level
