Cosalic Solution is a coal tar and salicylic acid scalp solution for a scalp that flakes, scales or builds up. Salicylic acid helps loosen and lift scale, and coal tar is a long-established ingredient in scalp care for flaking. You use it like a shampoo: massage it into a wet scalp, leave it for a few minutes and rinse. It helps the scalp look cleaner and feel more comfortable when used as directed.
Why choose Cosalic Solution?
Everyday shampoos wash the hair but often leave stubborn flakes stuck to the scalp. Cosalic pairs salicylic acid, which loosens built-up scale, with coal tar, a familiar ingredient for scaling. The contact time on the scalp gives both ingredients a chance to work before you rinse. It is made by Salve Pharmaceuticals, the company behind the Parasoft range.
Targeted Care for Flaking, Scaling & Scalp Build-Up

Step 1 — Prepare the Scalp
Part the hair and expose the affected scalp area so the solution can be applied directly where flaking and scaling need targeted care.

Step 2 — Apply and Target Flakes
Apply Cosalic Solution to the affected scalp areas as Salicylic Acid helps loosen accumulated scales and flakes, supporting more effective scalp cleansing.

Step 3 — Support Scalp Comfort
Allow the solution to remain on the scalp for the recommended time as Coal Tar supports the management of scaling and excessive skin-cell buildup associated with dandruff and similar scalp conditions.
How the two ingredients work together
-
Salicylic acid lifts flakes - It loosens the bonds between dead skin cells so that flakes and scale wash away more easily. That is why people look for a salicylic acid shampoo for flaky scalp.
-
Coal tar helps with scaling - Coal tar has been used for decades in scalp care. A coal tar shampoo for dandruff helps reduce the look of flaking and build-up over time.
-
Together, on a wet scalp - Salicylic acid clears the way, so coal tar reaches the scalp more evenly.
