Antifungal / Anti-dandruff
Last reviewed June 2026
Who is this for?
This is a medicated shampoo that combines two active ingredients — ketoconazole (an antifungal that kills the fungus causing dandruff and skin infections) and zinc pyrithione (which slows down flaking and controls itching on the scalp).
Inhibits fungal ergosterol synthesis by blocking lanosterol 14α-demethylase (CYP51), disrupting cell membrane integrity; simultaneously reduces scalp inflammation and sebum production through antimicrobial and antipruritic effects on the stratum corneum.

Apply the shampoo to wet hair and scalp, lather well, and leave it on for 3 to 5 minutes before rinsing thoroughly. Use it 2 to 3 times a week for the first 2 to 4 weeks, then reduce to once a week or as your pharmacist advises. It is for external use only — do not swallow.
If you forget to use it on your scheduled wash day, just use it the next time you wash your hair. Do not use it twice in one day to make up for a missed application.
Buy from a trusted pharmacy — products like Keratin Bluz Shampoo should be purchased from verified sellers, not roadside vendors where storage conditions are poor. Complete the full treatment course even if dandruff clears up early, otherwise it can come back. Avoid getting the shampoo in your eyes — if it happens, rinse immediately with plenty of water.
If you are using other medicated scalp treatments or hair creams, space them out and do not mix them with this shampoo at the same time. Avoid using harsh chemical hair relaxers or dyes on the same day you use this shampoo, as it may increase scalp irritation.

Is it safe to take Ketoconazole; with your other drugs?
If you are pregnant or breastfeeding, consult your doctor or pharmacist before using this shampoo, as ketoconazole can be absorbed through the skin in small amounts.
Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can be very hot, so do not leave it in your car or near a window. Keep the bottle tightly closed and out of reach of children.
