In the initial decade after the first identification of the hedgehog gene around 1980, there was almost no research devoted to the impact of the SHH pathway upon human hair. However, this started to change in the mid-1990s (e.g., this from 1998) and culminated in the seminal work on this subject that was published in the US in 1999: “Induction of the hair growth phase in postnatal mice by localized transient expression of Sonic hedgehog“.
The researchers from the University of Manchester’s Centre for Dermatology Research uncovered this finding through lab tests. They used samples containing scalp hair follicles from more than 40 male hair-transplant patients. The hair follicles were placed in a medium and treated with the drug. Researchers said that those hair follicles were able to grow again because it suppressed the actions of SFRP1. 

Ms. Imhof, who lives in Land O’Lakes, Fla., was skeptical. The company’s before and after photos seemed too good to be true. But she went for a consultation and made the cut. (Harklinikken’s products are not available to anyone with autoimmune illnesses like alopecia or baldness from scarring, or anyone who is unlikely to see at least a 30 percent increase in growth.)
Over the past year, the Hair Restoration Laboratories’ Professional Strength DHT Blocking Hair Loss Shampoo (and accompanying DHT Blocking Hair Loss Conditioner) has been a top seller on Amazon and many other sites. Combined, the daily use Shampoo and Conditioner has more DHT blockers than any shampoo/conditioner set presently available. Among the key DHT Blockers in this set are: Caffeine, Saw Palmetto, Black Cumin Seed Oil, Cayenne Fruit Extract, Rosemary Leaf Oil, Pumpkin Seed Oil, Green Tea Leaf Extract, Pea Extract and many more. By helping to block DHT, they should be a great asset in helping to halt the miniaturization of the hair follicles and regrow healthier and thicker hair.
3. Surgical hair replacement. If you opt for hair transplantation (which runs $5,000 and up), your dermatologist or hair-replacement surgeon will remove single hair follicles from the back of the head, near the nape of the neck, where your hair is fullest. Once those follicles are harvested, they are then dissected and reimplanted into an area of the scalp where hair is thinning. The procedure takes anywhere from three to six hours, and newly implanted hair will usually begin to grow on its own 3 to 12 months after the treatment session. Traditionally, hair transplantation required removal of an entire strip of scalp, Sadick says, but this new follicle-by-follicle technique looks more natural when it heals and allows patients to get heads of hair as dense-looking as before they started losing it.
Yet another company has made news this week for phase 2 trial progress. Concert Pharmaceuticals announced today that they have completed enrollment for their phase 2a trial using CTP-543 in alopecia areata. CTP-543 is an oral JAK inhibitor which acts on JAK 1 and 2, it’s also known as ruxolitinib. Concert’s version of ruxolitinib has been modified by the company’s proprietary deuterium chemistry technology which the company hopes will improve its effects on AA.
We’re not exactly sure about that “growth potential” stuff; for our purposes, the question is whether the product works to stop hair loss. Several of the confusing phrases the company uses actually address that question. The shampoo works to protect mitochondrial DNA, an important component in protecting and growing hair follicles, with fatty acids. It also contains ingredients which prevent further damage to the follicles. In other words, it protects and strengthens the hair you already have.
I hope you’re all having a good Friday and feeling good out there. Two weeks ago I posted my first “Feel Good Friday” update which contained a hilarious video of Deion Sanders showing off his new hairline from a 5,000+ FUE procedure he had in 2017. That video is now unable to embed because its owner changed his account to private. Coincidentally, a week after I shared that video I noticed that Deion posted a new video to his own Instagram account of him going back to his clinic for another FUE hair transplant to “comeplete his comeback”, in his own words.
Farrell makes what he calls “hair systems.” They’re not quite wigs or toupees—you can keep them on for weeks at a time. They cost more than a thousand dollars. Farrell was in New York for a week, holding meetings with clients in his hotel room. Now his rolling suitcases were packed. Malaysia, Singapore, South Africa, Russia: he’s almost always on the road, satiating international demand for high-end hair pieces.
Many other women, though, start noticing thinning hair on top of their heads. Doctors say the defining sign is a widening of the part. The hairline itself is usually intact, but the hair becomes less dense behind it. Doctors will often run a battery of tests to make sure there are no treatable medical conditions, such as anemia, thyroid problems, tumors, or hormonal problems. "Ninety percent of the time, it's normal," Patel said.
