Best Hand Blender – Ninja BN701 Professional Review
Q: Can this shampoo affect the actual hair color, or is it just for toning?
A: We’ve found it primarily tones, not alters, hair color. It’s ideal for maintaining vibrancy in bleached or lightened strands, and it even works on grey hair to neutralize yellow undertones. For fade-resistant color, pair it with Olaplex’s other products like No. 3 for optimal results.Q: Does it help with dryness or damage in addition to toning?
A: Yes! The formula contains reparative ingredients that work alongside the purple pigments to hydrate and strengthen hair. We’ve seen users report softer, more resilient strands after regular use, especially for those with chemically treated or damaged hair.Q: How long does the toning effect last?
A: the purple tones typically last 2-4 washes, depending on your hair’s porosity and how frequently you color or bleach it.We suggest using it consistently to maintain that fresh, radiant look without needing frequent touch-ups.
Q: What’s the best way to apply it?
A: We recommend massaging a generous amount into damp hair, focusing on roots and ends. Let it sit for 2-3 minutes before rinsing thoroughly. For deeper toning, you can mix it with a small amount of conditioner, but always follow with a clarifying shampoo if you’re using it often.
Q: does this shampoo have any side effects or risks?
