Frequently Asked Questions

Which hair type is this shampoo best for?

GRO Revitalizing Shampoo works for all hair types and textures, including fine or thinning.

I have color-treated hair, will this shampoo work for me?

Yes. GRO Revitalizing Shampoo is formulated without harsh sulfates (no SLS and SLES) and chemicals that strip your hair of its color.

How often should I wash my hair for best results?

It depends on your unique hair and scalp. Wash as often as needed based on your scalp’s oil production, hair texture and density — there’s no one-size-fits-all answer.
