Choosing the Right Hair Dye

Permanent

Long-lasting, full gray coverage, but contains ammonia/peroxide (e.g., Siglo, L’Oréal Excellence).

Semi-Permanent

No ammonia, fades in 4-6 weeks

Demi-Permanent

Lasts 12-24 washes, gentle on hair

Temporary

Washes out in 1-2 shampoos

Key Considerations

  • Skin Sensitivity? Opt for ammonia-free & PPD-free formulas.
  • Gray Coverage? Choose permanent dyes with high pigment.
  • Bold Colors? Semi-permanent fashion dyes work best.

Step-by-Step Application

For Permanent Dye:

  • Section Hair – Clip into 4 parts (front, sides, back).
  • Apply from Roots to Ends – Roots process faster, so do them last if touching up.
  • Massage Gently – Ensure even coverage, especially at the back.
  • Set a Timer – Follow box instructions (usually 20-40 mins).
  • Rinse with Cool Water – Helps seal the cuticle for longer-lasting color.

For Semi-Permanent Dye:

  • Apply on damp hair for even absorption.
  • Leave for 30+ mins (longer = more vibrant).
