Frequently Asked Questions
We answer some common queries about Density Thickening Shampoo.
If you have more questions you can submit a question below or visit our Help Centre to speak with our Customer Care Team.
We would recommend you consult your hairdresser/technician when considering using new products on your hair after having it chemically treated. Density Thickening Shampoo specifically is sulphate free and is therefore gentler on chemically treated hair, however results will vary depending on the type of chemical treatment you’ve had.
Yes, you can. We would recommend applying Minoxidil to a clean scalp and waiting 6 hours before applying any further topical scalp products. If you also wanted to use the Density Scalp Drops Foam or Toner, we would recommend using these at a different time, such as before bed if using Minoxidil in the morning. You can take Finasteride while using either Minoxidil or Density Drops (unless you were born female and are of childbearing age).
All cosmetic products are assessed by qualified experts for safety before they are allowed on the market. Unsafe products would not reach the market. If you have any concerns about products that you are using during pregnancy or when breastfeeding, we recommend that you consult a medical professional. We recommend discussing taking new supplements with a medical professional.
We have undergone huge amounts of testing on our Density range. All products have been through an independent user trial, where up to 100 people test each product without knowing which brand has made it. We have also undertaken several instrumental tests with laboratories, testing the volume enhancing properties and strengthening properties of our products.

My hairdresser noticed right aeway that my hair looked thicker. I am suffering from mild pattern baldness. So thank you, and will recommend to friends and colleagues.

After receiving treatment for cancer, my hair was left dry and had fallen out in places. The shampoo together with the conditioner turned my hair around in days. Amazing products.
A: All our formulations are suitable for colour-treated hair. We recommend not using Elasticizer Deep-Conditioning Treatment 72 hours before or after colour-treatment. In addition, we advise you not to use Vitamin C Jelly Treatment for the first 3 washes after having hair colour treated. As for our Pure Blonde Booster Shampoo and Booster Mask, all hair will react differently, so test a small section of your lightest hair before first use and wait at least two weeks after having hair coloured, bleached or permed before using. Finally, we advise not using Bond Builder Restorative Oil for the last 2 washes before having hair coloured, or directly after having hair coloured.
