Berk's Coal Tar Anti-Dandruff Shampoo, 8 fl oz — Extra-Strength 1.5% Coal Tar & 3% Salicylic

Berk's Full Spectrum is a concentrated medicated shampoo combining 1.5% coal tar, 3% salicylic acid, and 1.5% sulfur to reduce persistent flakes, scale, itching, and scalp buildup.

If over-the-counter dandruff shampoos haven't cleared your scalp, this extra-strength formula is created for tougher, recurring conditions such as seborrheic dermatitis and scalp psoriasis. The three active ingredients work together: coal tar helps slow skin cell production, salicylic acid exfoliates and removes scale, and sulfur supports flake control. The shampoo also includes rosemary oil to refresh hair and counterbalance the medicinal notes from the actives; that scent typically dissipates after rinsing.

How does this shampoo address stubborn flakes and scaling?

The combination of coal tar, salicylic acid, and sulfur targets different contributors to flaking. Coal tar helps reduce excessive skin-cell turnover, salicylic acid loosens and removes built-up scale, and sulfur assists in controlling visible flakes.

• 1.5% coal tar for slowing rapid scalp cell production
• 3% salicylic acid to exfoliate and dissolve scales
• 1.5% sulfur to help reduce visible flaking
• Formulated for repeat use when milder shampoos fail

How should I use it for best results and safety?

Use as directed on the label: apply to wet hair, lather, leave on the scalp briefly so ingredients can act, then rinse. Frequency can vary depending on severity; follow package instructions or consult a healthcare professional when unsure. Avoid contact with eyes and discontinue if irritation occurs.

• Wet hair thoroughly before applying
• Lather and leave on scalp per product directions, then rinse
• Use only as instructed; monitor for sensitivity
• Keep out of eyes and off broken skin

Will my hair feel or smell different after using this medicated shampoo?

You may notice a medicinal aroma while washing due to the active ingredients; that scent generally fades after you rinse. The formula includes rosemary oil to impart a fresher finish and help hair feel manageable rather than stripped.

• Temporary medicinal scent during application
• Rosemary oil to leave hair feeling refreshed
• No heavy residue when rinsed thoroughly
• Designed to balance scalp treatment with hair appearance

How long until I see improvement and when should I seek further help?

Some users notice reduced flaking within a few washes, but tougher cases may take several weeks of consistent use. If symptoms worsen, persist, or if you experience strong irritation, stop use and consult a healthcare provider for personalized guidance.

• Improvement may appear within multiple washes
• Continued use often needed for persistent conditions
• Stop and seek medical advice if irritation or worsening occurs
• Not a substitute for professional diagnosis or treatment

Who is this product for? Berk's Full Spectrum 1.5% Coal Tar Anti-Dandruff Shampoo is targeted at people whose flaking, itching, or scalp scaling hasn't responded to standard anti-dandruff shampoos and who need a stronger, medicated option. It's suitable for adults dealing with chronic or recurrent dandruff, seborrheic dermatitis, or scalp psoriasis who are looking for a single, concentrated 8 fl oz treatment with exfoliating and flake-reducing actives. If you have sensitive skin, are pregnant, or are using other topical scalp treatments, check with a healthcare professional before beginning use.
