How can you wash you hair after keratin treatment?

After a keratin treatment, it's essential to wait at least 72 hours before washing your hair to allow the keratin to fully set. When you do wash your hair, use a sulfate-free shampoo and conditioner to preserve the treatment's effects. Be gentle while washing and avoid using hot water, as it can strip the keratin. It's also advisable to limit the use of styling products with harsh chemicals.
