Considerations for hair washing frequency

Truth in advertising could facilitate realistic patient expectations
Both dermatologists and patients have expectations of what might result from an office visit. Dermatologists hope to meet the patient’s expectations and heal or address their concerns. Patients also have an expectation, and meeting those expectations yields patient satisfaction and a good patient/physician interaction.
Ingredients listings hint at concentration
Many of the new cellulite minimizing creams contain retinol as the ingredient that is called out on the front packaging. Remember that when an ingredient is called out on the packaging, this is not a claim and implies no efficacy.
