Excellent results with Malibu C Hard Water Wellness Remedy!! It safely removes any calcium buildup on relaxed hair. Prior to adding it to my relaxer regimen, I had noticed the hair was very tangled and difficult to comb out. The Malibu C Relaxer Wellness Remedy is excellent two weeks prior to a relaxer touchup. I've used the Hard Water Wellness System for 10 years and I am more than pleased with the results.
