Semi-permanent hair dyes are a gentle alternative to permanent color treatments, as they do not contain harsh chemicals like ammonia or alcohol. 

Semi-Permanent Hair Dyes

These dyes can add luster, deep glow, and delicate shimmering light reflections to your hair, enhancing its natural beauty. They are a great way to switch up your hair color without the commitment of a permanent change.

Here are some of the top choices for semi-permanent hair dyes available in the market.

Lime Crime Unicorn Hair

Lime Crime Unicorn Hair is a semi-permanent, long-lasting hair dye designed to fade gradually. Going for $17, it offers an incredible range of over 35 saturated shades to choose from. The dye is ready to use right out of the jar, making it perfect for at-home use. Formulated with conditioning ingredients like fatty acids and vitamins, it boosts shine and moisturizes hair. This vegan and cruelty-free formula is free of PPD, peroxide, and ammonia, ensuring a DIY-friendly experience that won't damage your hair.

Good Dye Young

Good Dye Young offers a clean semi-permanent dye that delivers ultra-vibrant color and hydrating ingredients. At $19, this dye lasts for 16 to more than 24 washes and is most vivid on level 10 hair. Infused with sunflower extract for UV protection and fragranced with bergamot essential oil, it deeply conditions hair while depositing color. To use, lighten your hair with the brand's Lightening Kit, then apply the dye directly onto dry hair for vibrant results.

Splat Ombre Dream Kit

This product offers a fun and expressive way to color your hair, priced at $13. Splat Ombre Dream kit includes everything you need for one dye job: dye, bleach, instructions, gloves, and more. For vivid, intense color, bleaching is recommended. The color lasts up to 30 washes, depending on your hair type. Follow the provided steps for best results, and use a sulfate-free shampoo to maintain color longevity.

Effects

Semi-permanent hair dyes coat the outer hair shaft, unlike permanent dyes that penetrate deep into the hair core. This means they are gentler on your hair and do not require bleaching. They can make your hair look more vibrant, especially if you have thin hair, as they add depth and volume. Additionally, they are easy to use and can be applied at home.

Things You Need to Know

Semi-permanent hair dyes typically last around six weeks or eight washes, depending on your haircare routine. To prolong the color, use shampoo and conditioner designed for colored hair and limit exposure to sun and chlorine. These dyes are safe to use, even on permed or previously dyed hair, as they do not contain bleach or ammonia. However, it's always a good idea to consult with a professional stylist before use.
