5 / 1000+ resultsresearch The Use of Body Hair with Scalp Hair for “Combination Grafting” to Enhance Visual Density of Hair Transplantation and Increase Coverage in Advanced Alopecia
This study found that using body hair along with scalp hair in hair transplantation can significantly increase visual density and improve coverage in patients with higher grades of androgenetic alopecia.
research A Novel, Drinkable Food Supplement Formulation Reduces Hair Shedding and Increases the Percentage of Anagen Scalp Hair Follicles in Females with Hair Loss
This study found that a novel drinkable supplement significantly increased hair density and reduced hair shedding over six months in women with telogen effluvium, although the authors emphasize the need for larger, placebo-controlled trials to confirm these promising results.
research Needle Transportable Semi-Automatic Hair Follicle Implanter and Image-Based Hair Density Estimation for Advanced Hair Transplantation Surgery
This study introduced a semi-automatic hair follicle implanter that can reduce surgery time and fatigue for both patients and surgeons, with effectiveness demonstrated in animal and clinical trials.
research Evaluation of the efficacy of a biomimetic peptide solution for rejuvenation of donor scalp and as storage media for hair follicle grafts during FUE hair transplantation
This study found that QR678 Neo® significantly enhanced hair regrowth, density, and shaft diameter in males with advanced androgenetic alopecia undergoing hair transplant surgery, compared to a conventional method, making it a promising adjunct treatment option.

5 / 1000+ resultscommunity Redensyl for Hair Loss — What It Can and Can’t Do
Redensyl is a plant-based treatment that may support hair regrowth by reactivating dormant follicles and improving hair density, especially in early-stage thinning. It is not a miracle cure and results vary; it is less proven than Minoxidil or Finasteride and may cause scalp irritation.
community BREAKTHROUGH: I’m a radiochemist and discovered a radioactive isotope scalp serum that OUTPERFORMS Minoxidil and 5-AR inhibitors! (Lab Data Inside)
A satirical post where someone claims to have developed a radioactive isotope scalp serum using Polonium-210 that outperforms Minoxidil and finasteride for hair regrowth. The serum reportedly stimulates DNA repair in hair follicles, leading to significant hair density increase, but the post is met with skepticism and concerns about safety.
community Can those who had Hair Transplant use PP405 and Clascoterone? Scalp blood supply limitation question
Using PP405 and Clascoterone after a hair transplant may not cause issues if the transplant didn't achieve native density, but could lead to competition for blood supply if it did. Some users suggest waiting for these drugs to be available, as they might not significantly impact blood supply or regrowth.
community Trying to understand severe shedding and progressive density loss after a successful hair transplant
The user is experiencing severe shedding and progressive hair density loss after a successful hair transplant, despite using finasteride, minoxidil, microneedling, and scalp treatments. Suggestions include trying stronger treatments like oral dutasteride, topical RU58841, and higher doses of oral minoxidil.
community Dutasteride + oral minoxidil: strong regrowth by Jan 2026, then mid-scalp density loss without current shedding
The user experienced hair regrowth with dutasteride and oral minoxidil from October 2025 to January 2026, but mid-scalp density decreased afterward despite continued treatment. Ketoconazole improves scalp condition, but stopping it worsens hair appearance.

9 / 44 results- Does metformin help control DHT levels that trigger androgenic alopecia? Small studies have found that metformin lowers circulating androgens in women with PCOS, but no published study has measured scalp DHT, 5-alpha reductase activity in the follicle, or hair density in anyone taking it — so its effect on pattern hair loss is untested, and it is not a DHT blocker.
- Will scalp micropigmentation damage my existing hair or follicles? Providers say SMP sits above the hair follicles and does not harm them. No study has tested this, and infection or scarring from any tattoo can affect the skin.
- Will scalp micropigmentation grow my hair back? Scalp micropigmentation does not grow hair back; it only enhances appearance.
- Does sh-Polypeptide-7 stimulate hair follicles or reduce scalp inflammation? sh-Polypeptide-7 is the INCI name for a lab-made form of human growth hormone (somatotropin) — not EGF, which is sh-Oligopeptide-1. Growth hormone and IGF-1 signalling is documented in hair follicle biology, but there is no published human trial of sh-Polypeptide-7 applied to the scalp for hair growth or scalp inflammation.
- What is sulforaphane, and what does research say about scalp and hair follicles? Sulforaphane is a compound from broccoli and related vegetables. Lab and mouse studies suggest effects on follicle cells and on DHT breakdown, but it has not been tested for hair in people.
