The Weightless Collection is the result of five years of formulation and a lifetime of purpose. Founder Merian designed every product to reflect both her Mesopotamian roots and her dedication to science-first, clean beauty. From ancient botanicals like rosemary and aloe, to advanced, patented actives like Volunix Bio-Activesā„¢ Blend and the exclusive PGenics Hydra, each formula is thoughtfully crafted to deliver hydration without heaviness. Even the scent tells a story: Golden Nectar, a 100% plant-derived fragrance, and Desert Cream Rose. Inspired by the way scents were first created, naturally, intentionally, and with meaning. This is Texture Innovationā„¢, honoring tradition and redefining the future of hair care. #BounceCurl #FounderLed #HeritageAndInnovation #PGenicsHydra #PlantDerivedFragrance #WeightlessCollection  @The Curly Family

This is Sharon my bff & brand marketing manger at @bouncecurl ! We have transformed her curls over the past 10 years from heat damage to beautiful juicy coils! She actually has fine textured hair but a lot of it. So our weightless collection is perfect for her when she wants more volume 🩷 she used to put way too much heat on her curls & they would get damaged after one straightening session, but now she uses heat protectors (in our thermal guard weightless leave in) & ensures her heat temp is not extremely high (below 400). & she’s been in the clear!  @ms.classic_li  #coils #curls

I FINALLY got a chance to try the new Bouncecurl products that are supposed to deliver weightless moisture, and I will say they definitely did not disappoint on the moisture!  Next time I’m going to pair with a hairspray or something with a little bit more hold but I really loved my results and the SHINE!   I ended up using the leave in to refresh a few pieces on day 3 too! I like that it went on my dry hair easily and didn’t weigh it down!  #curlyhair #3b #shinyhair #washday #3c
