Nº.9 BOND PROTECTOR Voedend Haarserum

I've been using this on my clients after every blowout and the difference in how their hair holds up is noticeable, especially with heat styling. Tangles are way easier to brush through the next day too. A little goes a long way, so the bottle justifies its price.

I've been using this serum on my own hair before styling and the difference in how long my curls hold is noticeable. It's lightweight and doesn't leave that greasy feel, but my ends definitely tangle less during the day. Worth it for the heat protection alone.

My clients' hair has been so much easier to detangle since I started using this serum before blow-drying, and the weightless feel is a huge plus—no greasy residue left behind. The heat protection is the real deal, my foils are holding their style way longer even on humid days.
