Botulinum Toxin for Scalp Conditions: A Systematic Review

This study found that one session of intradermal botulinum toxin type A injection decreased scalp sebum secretion and perception of greasiness more effectively than saline for up to 3 months.

This study concluded that both botulinum toxin A and multivitamins mesotherapy effectively treat telogen effluvium, but a single botulinum toxin A session may be preferable due to its convenience and comparable efficacy.

This study found that combining botulinum toxin A injections with finasteride and minoxidil increased hair density in patients with androgenic alopecia more effectively than finasteride and minoxidil alone.

This article provides information on data availability but reports no new research findings.

This study found that for treating androgenetic alopecia, LC hair essence serum injections provided excellent results with fewer side effects compared to botulinum toxin A, which also showed significant efficacy but with higher associated costs and more frequent side effects.

In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

This article reports a case of a 30-year-old woman developing alopecia after a hyaluronic acid injection, with trichoscopic findings described for the first time.

In this pilot study, botulinum toxin was found to be a safe and effective treatment for androgenetic alopecia in most participants, though larger studies are needed to confirm these findings.

In this case study, repetitive botulinum type A toxin injections led to almost complete resolution of severe chronic pain in a patient with Parry-Romberg syndrome.

This case report describes a 33-year-old woman whose unilateral occipital pain and localized alopecia were only responsive to onabotulinumtoxin A, suggesting it might be a form of cephalalgia alopecia or nummular headache.

In this study, BTXA injections did not effectively treat recalcitrant alopecia areata or improve hair regrowth in most patients, suggesting its limitations as an alternative therapy.

This study suggests that Botox injections may increase hair count and reduce hair loss in men with androgenetic alopecia, potentially through increased blood flow and oxygen to the scalp.

Botulinum A toxin injections reduced pain and promoted hair regrowth in a woman with a rare form of alopecia areata.
