Poly Tar Shampoo on Permed Hair: Why It's Not Recommended

Poly tar shampoo (coal tar) is generally contraindicated for permed hair.

Why

• High alkalinity (pH 9–10): Swells hair shaft, breaks disulfide bonds reformed during perming → destroys curl pattern.
• Harsh surfactants: Strip lipids, increase porosity, cause frizz and breakage.
• Tar residue: Coats hair, dulls shine, attracts dirt.

Better Choices for Permed Hair

• Sulfate-free, pH-balanced (4.5–5.5) shampoos: Preserve curl integrity, moisture.
• Conditioner-washing (co-wash): Mild cleansing, high conditioning.
• Ingredients to look for: Panthenol, hydrolyzed proteins, glycerin, oils (argan, jojoba), cationic polymers.
• Deep conditioning weekly.

When Coal Tar Is Indicated

• Scalp psoriasis, seborrheic dermatitis, severe dandruff.
• If needed, apply only to scalp, avoid lengths, limit contact time, follow with intense conditioner.

Consult your stylist for product recommendations matched to your perm type and scalp condition.
