  • Great product!
Size: 13.5 Fl Oz (Pack of 1)
Smells good, makes my hair look great. Will buy again!

  • Love!
Size: 13.5 Fl Oz (Pack of 1)
Works really well. Not heavy. Leaves my hair silky and hydrated!

  • Smooth proof is AMAZING for wavy hair!
Size: 33.8 Fl Oz
This stuff is top tier. I have long, mid-high density hair that is naturally heavy wave/light curl (2C-ish). I do have lightened and vibrantly colored hair, just one wash tamed about 80% of my frizz without any other Smooth Proof products added, and my hair felt VERY soft and much easier to brush. I got hooked after my hair stylist used it on me after double processing, and my hair came out mirror glossy with her Bioionic flat iron! It has that pleasant, iconic Biolage fragrance to it. This may not be quite hydrating enough for *very* dry hair, but add in a hydrating hair mask and it would be perfect. If the price stays at 27.99, the 33oz bottles are an insane value for the quality! ... show more

It’s very smooth, with a typical scent for shampoos. Very big size so the value for money is great. Great appearance and veryyy moisturizing.

  • Great Conditioner
Size: 33.8 Fl Oz
Finally recieved my order after the 1st shipment was lost/delivered to the wrong address. Absolutely love this shampoo and conditioner. Just in one use my hair feels and looks great. A little pricey but well worth the cost. Lathers great and you don't need to use much. This will be my only shampoo and conditioner from now on. ... show more

  • Best hair product on the market
Size: 13.5 Fl Oz (Pack of 1)
This shampoo really repairs your hair. After just a few washes, I can brush it with no more tangles, it's no longer frizzy or looking like an afro. I was nervous about paying so much but I am hooked. My late wife turned me on to this about 12 years and I am forever grateful. I just spent the last ten years homeless since she passed away but I recently found recovery and a job that allows me to afford it and within just a few washes, just like last time, I am no longer walking around with a tangled mop on my head. ... show more
