There are no official guidelines to assist in answering this question. I will search for relevant research papers instead.
The FDA Drug Labels for ketorolac (PO) do not address this question.
From the Research
Ketorolac and Hair Growth
There is no direct evidence to suggest that ketorolac causes hair growth. The available studies focus on the drug's analgesic and anti-inflammatory properties, as well as its potential side effects, but do not mention hair growth as a possible effect.
Drug-Induced Hair Loss
- Drugs may cause hair loss, stimulate hair growth, or induce changes in hair shape and color, as noted in studies 1, 2.
- Drug-induced hair loss is usually reversible and is often a consequence of a toxic effect on the hair follicle matrix.
- The relationship between drug intake and hair loss has only been proven for a few agents, and ketorolac is not mentioned as one of them.
Hair Growth Promotion
- A study on Necrosulfonamide 3 found that it promotes hair growth and ameliorates DHT-induced hair growth inhibition, but this is not related to ketorolac.
- Another study 4 reviewed the clinical efficacy of popular oral hair growth supplement ingredients, but did not mention ketorolac.
Conclusion on Available Evidence
There are no research papers that directly investigate the effect of ketorolac on hair growth, and the available studies do not provide evidence to support the claim that ketorolac causes hair growth 1, 5, 2, 3, 4.
