Can I use this spray together with my regular shampoo, conditioner, and styling products?

The spray is designed as an add-on step for the root area, not a replacement for your cleanser or conditioner. A typical sequence: wash hair with your normal shampoo, rinse, towel-blot excess water, then apply Exiderm spray to the scalp. Massage in and let it sit for a few minutes until the scalp feels dry to the touch. After that, apply conditioner or mask to the mid-lengths and ends only — avoid the roots so you don't dilute the leave-on layer. Finish with your usual leave-in treatments, heat protectant, or styling products.

Because the formula is water-based and leaves no heavy residue on the hair shaft, it does not interfere with mousses, sprays, or oils applied afterward. If you use a medicated shampoo (for example, anti-dandruff or prescription), you can still use this spray on non-medicated wash days, but check with your dermatologist if you are on a specific scalp treatment plan.

One practical tip: if you apply a lot of styling products near the roots (dry shampoo, volumizing powder), wash the scalp thoroughly before the next Exiderm application so the spray contacts skin, not product buildup. This keeps the botanical complex and birch tar working on the scalp surface as intended.
