Buying Guide
What matters most for chemically treated hair
- Sulfate-free formulas help retain moisture and protect color by avoiding harsh cleansing agents.
- Bond-strengthening ingredients (such as bond repair complexes or keratin) can reduce breakage after chemical processing.
- Hydration and humectants prevent frizz and improve manageability without weighing hair down.
- Color protection and fade-resistant formulas extend vibrancy after lightening or dyeing.
- Scalp compatibility is essential; choose products that suit your scalp type and tolerance to scents or botanicals.
Choosing by hair type and processing level
- Fine, color-treated hair: Lightweight, sulfate-free formulas with color protection and volumizing properties (e.g., Bond Repair+ or moisture-focused shampoos without heaviness).
- Coarse or porous hair: Rich hydration, strengthening actives, and frizz control help reduce dryness and breakage.
- Very damaged or bleached hair: Bond-building or keratin-rich formulas paired with a matching conditioner can improve texture and reduce breakage.
How to use for best results
- Follow bond-repair or keratin-focused products with a compatible conditioner to seal in benefits.
- For color-treated hair, rotate with color-safe formulas to balance cleansing strength and moisture.
- If using a sulfate-free shampoo, expect slower lather and ensure thorough rinsing to remove product buildup.
Key ingredient considerations
- Protein (keratin, silk, collagen) supports strength but may cause stiffness if overused on fine hair.
- Humectants (glycerin, hyaluronic acid) attract moisture but can leave hair feeling heavy in high humidity.
- Bond-restoring compounds (Bond + Amino acids, OLAPLEX technology) target internal hair structure for durable repairs.
