Wella Wellaplex No.3 Hair Stabilizer . Unused (full container), but I didn't keep the box so not in original packaging. From the website: Wella Wellaplex No.3 Hair Stabilizer 100ml is a weekly at-home treatment that strengthens, smooths, and softens hair after coloring or lightening, extending the benefits of the Wellaplex in-salon service. Hairdresser recommended I try it (for thin, hair) . However, I decided to go back to natural products and didn't end up using it. I just hate to waste it though and would prefer it got used by someone. Happy to accept an offer. I can post at your cost or arrange pick up in Hamilton. Nioxin Shampoo and Nioxin Conditioner are also available and work well together apparently (see separate listings).
