Atopic Dermatitis: a Short Summary
- Known limitations: a reminder
- the result might might be good but “complete” hair removal is not possible
- ineffective on white hair
- Combining medical treatments with lasers
- Ornithin decarboxylaser (eflornithine) is a known treatment against hirsutism and is a known medical topical treatment to induce hair thinning.
- The presenter sought to evaluate the effect of topical eflornithine + lasers (abstract: http://www.ncbi.nlm.nih.gov/pubmed/17270315)
- Monthly treatment sessions with the alexandrite laser for 6 months (one side treated with l+e and the other treated with laser alone)
- Results: with eflornithine and lasers works better after 3 months. Although the difference is less visible after 6 months, it remains statistically significant.
- Laser hair removal can induce hair growth:
- It is a paradoxical effect
- The presenter reports a patient undergoing 7 Alexandrite laser sessions (energy 23-47 J/cm2) developeing hair growth.
- Comments:
- in an Iranian study in 2009 in including 991 patients, a paradoxical effect was observed in 5.5% of cases.
- When combining the results from several studies and reports, the overall risk seems to be around 5%
- Solution: inform the patient of the risk of paradoxical hair growth
