I am copying it below for the sake of discussion. But I think they basically threw the kitchen sink at this patent, which is usually what they do in patents not to keep any option off the table... they have RU, estrogen, finasteride, caffeine...
But there are some good candidates obviously. I have seen studies about copper peptides and wound healing for example
"2018-10-18
Application filed by Follica Inc"
This is a broad patent application that includes every conceivable method and degree of wounding. The Most recent trial data from Follica provides a more concise description of the initial treatment.
"In one aspect, a method of integumental perturbation described herein disrupts skin to a depth of between 30 μm to 200 μm,... and preferably to approximately 100-150 μm."
"the microneedle array can disrupt skin at a depth of 100 microns to 4000 microns."
"In certain aspects the methods described herein are used to replenish hair in scalp that was used or could be used as a donor site for hair transplant surgery."
"In an embodiment, the treatment regimen is repeated multiple times to build up hair density over time."
The patent is a catch all, and most of it has not been tested:
"In some embodiments, integumental perturbation is to a skin depth of 100-500 μm. In some embodiments, integumental perturbation is to a skin depth of less than 500 μm. In some embodiments, integumental perturbation is to a skin depth of 500-1000 μm. In some embodiments, integumental perturbation is to a maximum skin depth of about 1 mm. In some embodiments, integumental perturbation is to a skin depth of about 1 mm or more. In some embodiments, integumental perturbation is to a maximum skin depth of about 2 mm. In some embodiments, integumental perturbation is to a skin depth of about 2 mm or more. In some embodiments, integumental perturbation is to a skin depth of 1 mm to 3 mm. In some embodiments, integumental perturbation is to a skin depth of 1 mm to 5 mm. In a particular embodiment, the depth of integumental perturbation does not exceed 500 μm. In a particular embodiment, the depth of integumental perturbation does not exceed 1 mm. In a particular embodiment, the depth of integumental perturbation does not exceed 2 mm."

In some embodiments, the hair growth-promoting agent treatment comprises treatment with a copper peptide(s), preferably applied topically, or another compound with superoxide dismutation activity. In some embodiments, the hair growth-promoting agent treatment comprises treatment with an agent that increases nitric oxide production (e.g., arginine, citrulline, nitroglycerin, amyl nitrite, or sildenafil (v****)). In preferred embodiments, such compounds are administered further in combination with a catalase or catalase mimetic, or other antioxidant or free radical scavenger.

In some embodiments, the hair growth-promoting agent treatment comprises treatment with a compound that mobilizes bone marrow-derived stem cells (e.g., growth factors such as G-CSF and/or chemical agents such as plerixafor (Mozobil®)); and/or that regulates the differentiation of these stem cells into gender-specific specialized human hair follicles (e.g., using agents such as finasteride, fluconazole, spironolactone, flutamide, diazoxide, 11-alpha-hydroxyprogesterone, ketoconazole, RU58841, dutasteride, fluridil, or QLT-7704, an antiandrogen oligonucleotide, cyoctol, topical progesterone, topical estrogen, cyproterone acetate, ru58841, combination 5α-reductase inhibitors, oral contraceptive pills, and others in Poulos & Mirmirani, 2005, Expert Opin. Investig. Drugs 14:177-184, incorporated herein by reference, or any other antiestrogen, an estrogen, or estrogen-like drug (alone or in combination with agents that increase stem cell plasticity; e.g., such as valproate), etc., known in the art), that can result in, e.g., the appearance of specialized follicles having features that are different from natural follicles in the target location of skin.

In some embodiments, the hair growth-promoting agent treatment comprises treatment with one or more agents that counteract age-related hair thinning and/or hair follicle cell senescence (also referred to herein as “anti-senescence agents”) for example, antioxidants such as glutathione, ascorbic acid, tocopherol, uric acid, or polyphenol antioxidants); inhibitors of reactive oxygen species (ROS) generation, such as superoxide dismutase inhibitors; stimulators of ROS breakdown, such as selenium; mTOR inhibitors, such as rapamycin; or sirtuins or activators thereof, such as resveratrol, or other SIRT1, SIRT3 activators, or nicotinamide inhibitors.

In some embodiments, the hair growth-promoting agent treatment comprises treatment with one or more agents that induce an immune response or cause inflammation, such as, e.g., tetanus toxoid, topical non-specific irritants (anthralin), or sensitizers (squaric acid dibutyl ester [SADBE] and diphenyl cyclopropenone [DPCP]). While not intending to be bound by any theory, it is thought that by contacting these agents to the skin, lymphocytes and hair follicle stem cells may be recruited to skin. In some embodiments, the hair growth-promoting agent treatment comprises treatment with a chemical or mechanical (such as those discussed infra) treatment that induces an inflammatory process in the skin. While not intending to be bound by any theory, inducing inflammation in the site where hair growth is desired helps to recruit stem cells to the tissues that drive the formation of new follicles.

In some embodiments, the hair growth-promoting agent treatment comprises treatment with an antiapoptotic compound. In one embodiment, the antiapoptotic compound is not a Wnt or a Wnt agonist."
