How can I avoid it?

Watch out for common chemical irritants that may trigger a seborrheic dermatitis flare-up. Often ingredients found in well known shampoo's or conditioners brands can irritate. Even some brands labeled 'hypoallergenic', 'sensitive' or 'natural' contain unnecessary additives & harsh chemicals.

In particular, look out for fragrances, colors and harsh preservatives such as parabens (butylparaben, propylparaben, methylparaben) or methylisothiazolinone.

For shampoo's be especially carefully to avoid SLS (sodium laureth sulfate) or CAPB (cocamidopropyl betaine)- both of these ingredients have been known to trigger contact dermatitis.
