Jack Black Double-Header 2-in-1 Shampoo & Conditioner, 16 oz — Sulfate-Free, Coconut & Kelp for Gentle Daily Cleansing

Jack Black Double-Header is a 2-in-1, sulfate-free shampoo and conditioner that removes oil and product buildup while lightly conditioning and soothing the scalp for healthier-looking hair.

This PureScience-formula cleansing conditioner blends coconut oil and kelp extract to lift grime and excess oil without stripping natural moisture. Designed for everyday use, it produces a creamy lather that detangles, softens, and calms the scalp while leaving hair manageable and with a subtle sheen. The 16 oz size suits home grooming routines and reduces the need for multiple bottles.

How does this product remove oil and product buildup without drying hair?

Formulated without sulfates, the Double-Header uses mild surfactants that break up sebum and styling residue while protecting the hair’s natural oils. Coconut-derived cleansing agents gently lift build-up and kelp extract helps manage moisture so strands don’t feel stripped. The result is cleaner hair that retains softness and elastic texture.

• Sulfate-free surfactants that cleanse without harsh stripping
• Coconut oil supports gentle removal of grease and residue
• Kelp extract balances moisture while boosting manageability

Will this product condition and detangle after a single use?

Yes — the hybrid shampoo/conditioner is formulated to condition lightly while it cleanses, leaving hair easier to detangle straight out of the shower. It won’t replace a heavy rinse-out conditioner for very dry or curly hair, but provides sufficient slip for most short-to-medium hair types. Hair feels softer and combs through with less pulling.

• Light conditioning agents for everyday detangling
• Improves softness and reduces friction during combing
• Suitable for routine use to maintain manageability

Is this safe for sensitive scalps and color-treated hair?

The sulfate-free PureScience formula is milder on the scalp than traditional sulfates and contains soothing botanicals to reduce irritation. While it’s gentler and less likely to accelerate color fade than harsh cleansers, results will vary—color-treated hair may still benefit from a dedicated color-safe shampoo for longer-lasting vibrancy. Patch-test if you have a hypersensitive scalp.

• Sulfate-free for gentler scalp cleansing
• Botanical extracts to help soothe irritation
• Generally safe for color-treated hair; for best color retention use with color-safe regime

How do I use Jack Black Double-Header for best results?

Massage a quarter-size amount into wet hair and scalp until a creamy lather forms, then rinse thoroughly. Repeat if hair is especially oily or product-laden. For thicker, very dry hair, follow with a targeted conditioner on mid-lengths and ends as needed.

• Apply to wet hair, massage into scalp and lengths, rinse
• Repeat once for heavy build-up or oily scalps
• Follow with specific conditioners for extra hydration if required

Who is this for: Jack Black Double-Header is ideal for men and women seeking a convenient, everyday cleansing conditioner that removes oil and styling residue while providing light conditioning and scalp comfort. It works well for normal to slightly oily hair, those who prefer shorter grooming routines, and anyone wanting a milder, sulfate-free formula with botanical support. If you have very dry, textured, or color-treated hair needing deep moisture or specialized care, consider pairing this product with a richer rinse-out conditioner.
