February 2022 in “Acta Biomaterialia” In this study, researchers found that dissolving microneedles made with hyaluronic acid enhanced the effectiveness of minoxidil in reducing hair loss and promoting hair growth in alopecia-affected mice more effectively than topical minoxidil alone, while using only 10% of the drug amount.
10 citations
,
September 2021 in “JAMA Dermatology” This study reports that persistent chemotherapy-induced alopecia in breast cancer patients frequently resembles androgenetic alopecia, and treatment with minoxidil, alone or with antiandrogens, improved hair density in many cases.
42 citations
,
April 2021 in “JCI insight” In this study, selective inhibition of JAK3 signaling effectively prevented and reversed alopecia areata in a mouse model, while JAK2 inhibitors did not restore hair growth.
15 citations
,
November 2020 in “Pharmaceutics” In this ex vivo and mouse model study, Tofacitinib-loaded nanoparticles demonstrated enhanced delivery of the drug into hair follicles and reduced inflammatory effects compared to conventional forms, indicating potential for safer, topical use in treating alopecia areata.
60 citations
,
October 2020 in “Journal of Controlled Release” This study found that curcumin nanocrystals efficiently penetrated hair follicles down to the lower infundibulum in an ex-vivo pig ear model, regardless of the gel vehicle used, though passive dermal penetration varied with the vehicle’s skin hydrating properties.
13 citations
,
September 2020 in “Sensors” This study used melamine formaldehyde particles to measure a pH gradient along the hair shaft, showing a significant pH decrease from the hair sheath to the external shaft.

April 2020 in “Drugs” Emerging therapies like JAK inhibitors show promise for hair regrowth in alopecia areata.
54 citations
,
September 2019 in “Journal of the European Academy of Dermatology and Venereology” This study found that tofacitinib shows reasonable effectiveness for treating alopecia areata with mild adverse effects, although more large-scale randomized trials are needed to fully assess its safety and efficacy.
9 citations
,
February 2019 in “BMC cancer” This study found that M30 may protect against cyclophosphamide-induced alopecia in mice by enhancing hair growth and preventing abnormal hair, suggesting its potential as a treatment.
66 citations
,
December 2018 in “Dermatology” This study found that oral JAK inhibitors, ruxolitinib and tofacitinib, are effective and well-tolerated for treating severe alopecia areata, with a similar degree of hair regrowth and relapse rates, but ruxolitinib induced faster initial hair regrowth.
16 citations
,
October 2018 in “Experimental Dermatology” This study suggests that mesenchymal stem cell therapy may improve cell viability and regulate key signaling pathways in vitro for treating alopecia areata.
50 citations
,
December 2017 in “Nanoscale” This study found that polymeric micelle formulations significantly improved the targeted delivery of adapalene to hair follicles compared to standard Differin® products, which suggests potential advantages in treating hair follicle-related conditions and reducing side effects.
290 citations
,
December 2017 in “Journal of The American Academy of Dermatology” This article reviews the epidemiology, clinical evaluation, and pathogenesis of alopecia areata and highlights recent advancements, but it does not report new clinical findings.
29 citations
,
April 2017 in “Macromolecular bioscience” In this study, researchers developed a pH-sensitive dendritic polyglycerol nanogel to measure pH inside hair follicles using an ex vivo porcine ear model, finding that the pH increases from 6.5 at the skin surface to 7.4 in deeper follicle areas, without observed toxicity.
14 citations
,
July 2016 in “Environmental Toxicology and Pharmacology” In this animal study, cedrol treatment reduced chemotherapy-induced alopecia in mice by preventing hair follicle damage, while minoxidil did not prevent alopecia under similar conditions.
25 citations
,
November 2015 in “Journal of Ethnopharmacology” This study found that Cacumen platycladi extract significantly promoted hair growth and reduced dihydrotestosterone levels by inhibiting 5α-reductase activity in an androgen-sensitive mouse model.

,
August 2014 in “Nature medicine” This study found that JAK inhibitors promote hair regrowth in both mice and human alopecia areata cases by blocking key immune pathways involved in disease development.
62 citations
,
December 2013 in “Aaps Journal” This research reported that squarticles, nanoparticles made from sebum-derived lipids, enhanced the follicular delivery and skin accumulation of diphencyprone and minoxidil, indicating effective drug deposition with reduced systemic absorption in alopecia treatment.
