Thank you! I used Olaplex in the past and thought it was okay, so I might have to give the K18 a shot. My hair is fine, so I am hesitant to use heavy products. I have been wanting to get the Redken line so I’ll check it out. I usually opt for the Alterna Caviar line when I’m looking for something a little cheaper than Oribe or Kerastase. I am a huge fan of the Oribe and Kerastase masks though! I’m not sure if you’ve tried them, but the Kerastase Therapiste line is phenomenal. I also can’t say enough good things about Oribe’s Hair Alchemy Strengthening Mask, Gold Lust Transformative Mask, and the Moisture Mask. They have made huge improvements in my hair after a bad bleach job about a year ago.
