I’ve been using the bond rehab salve for over a year and I love it! Halts breakage in its tracks. My natural hair tends to like strengthening products anyway (medium to fine strands), so it was no surprise to me. I enjoyed that it was more affordable than olaplex and it had both a protein and a bond strengthener in the formulation. Smells nice and feminine. I use it twice month for about 20 minutes.
I’ve also used the multitasking conditioner from the purple strength line and it was also a good product. Smells the same as the bond rehab salve (I assume all the products in the purple strength line smell the same). Definitely a light strengthening product, and it can be used as a rinse-out or leave in conditioner. I realized that with my use of the salve, I didn’t need the conditioner, so I discontinued use, but I still like the product overall.
