Acorn Disease (Acomia): Its Nature, Onset, and Present-Day Remedies
In the ongoing quest to combat hair loss, researchers are exploring additional immune-targeted therapies for various types of alopecia, including biologics and small molecules [1]. One such emerging therapy is the use of Janus kinase (JAK) inhibitors, which have shown promising results for Alopecia Areata (AA) [1].
JAK inhibitors, both oral and topical, represent a significant recent advance due to their ability to target the autoimmune basis of AA and promote rapid hair regrowth [1][2]. Several JAK inhibitors have gained FDA approval or are in advanced clinical trials for AA.
For instance, Leqselvi (deuruxolitinib), approved for adults with severe AA, demonstrated fast and significant improvement in hair regrowth in large-scale trials, with a primary endpoint of reducing scalp hair loss severity within 24 weeks [3]. Another promising JAK inhibitor, Ritlecitinib, an oral selective JAK3/TEC inhibitor, has shown efficacy by inhibiting pathogenic cytokines involved in AA, resulting in good hair regrowth and a favorable safety profile with mostly mild adverse events [4].
The mechanism behind JAK inhibitors lies in their ability to block signaling pathways involved in the autoimmune attack on hair follicles, leading to disease reversal and hair regrowth. They offer a better benefit-to-risk ratio compared to traditional systemic immunosuppressants like corticosteroids and cyclosporine, with fewer and milder adverse events reported so far [2].
Other treatments for AA include platelet-rich plasma (PRP) injections, offering regenerative potential, though their long-term efficacy and safety require further clinical validation [1][2]. Low-dose oral minoxidil, which promotes hair regrowth, can also be useful as adjunctive therapy across alopecia types, given appropriate patient selection and monitoring [1]. Low-level laser therapy is gaining traction as a noninvasive adjunct, particularly for androgenetic alopecia, but its role in AA is ancillary [1].
As we look to the future, the focus shifts to optimizing the long-term safety and efficacy of JAK inhibitors, combining these with other treatments, identifying biomarkers for treatment response, and strategies to maintain remission after stopping therapy [2].
It's important to note that alopecia, particularly in visible areas like the scalp and eyebrows, can negatively impact emotional and psychological well-being. Alopecia remains a clinical diagnosis best managed by dermatology professionals.
In the case of Scarring Alopecia, novel immune modulating agents are emerging therapies, while Telogen Effluvium is characterised by diffuse hair shedding and treatment often involves addressing the underlying cause and using Minoxidil. Androgenetic Alopecia, characterised by gradual scalp hair thinning, common treatments include Minoxidil, Finasteride, and hair transplant.
The term "Acomia" is considered archaic and should be replaced with "Alopecia" to avoid confusion. Refinements in LLLT technology and device delivery systems are enhancing treatment options as non-invasive adjuncts for alopecia. Stem cell therapy and platelet-rich plasma (PRP) injections show potential in stimulating follicular regeneration and enhancing hair density in alopecia.
In summary, JAK inhibitors represent a major recent advance and are now approved treatments for severe alopecia areata, offering faster and more effective hair regrowth with a more favorable safety profile compared to prior options. Their use alongside emerging adjuncts and supportive therapies is reshaping the AA treatment landscape.

Skin care and health-and-wellness are interconnected aspects, as effective solutions for certain medical-conditions, such as alopecia, can significantly impact an individual's emotional and psychological well-being. Medicine, particularly the emergence of Janus kinase (JAK) inhibitors, has revolutionized the treatment landscape for alopecia, especially Alopecia Areata, with promising results and a favorable safety profile.
