What Aftercare advice that should be given to a client after a shampooing and conditioning service?

After a shampooing and conditioning service, advise the client to avoid washing their hair for at least 24-48 hours to allow the scalp and hair to recover and maintain moisture. Recommend using a sulfate-free shampoo and conditioner to prolong the benefits of the service. Additionally, suggest minimizing heat styling and using a heat protectant if they choose to use styling tools. Encourage regular trims and deep conditioning treatments to keep their hair healthy and hydrated.
