Q&A

Is it recommended to wash the hair daily with the shampoo and conditioner?
Hi Diego, great question! Our Shampoo and conditioner are formulated to support scalp and hair health without weighing things down, so they can certainly be used daily if you choose to! We do generally recommend this for best results. That being said, all have different needs, when it comes to washing and conditioning, so you may want to explore what will work best for your hair's length and texture.
