Luster Shortlooks Color Relaxer 3-n-1 Diamond Black — Smooths, Colors & Conditions for Glossy, Frizz-Free Hair

Luster's Shortlooks Color Relaxer 3-n-1 Diamond Black smooths, colors and conditions hair in one treatment for visibly straighter, glossy results.

This all-in-one formula from Luster is designed for people seeking straightened hair while adding rich Diamond Black pigment and deep conditioning. The product is crafted without ammonia or peroxide and is intended to reduce frizz, improve manageability and boost shine across a range of hair textures. It’s marketed to deliver strength and body without leaving stains on the scalp when applied correctly.

How does the 3-n-1 formula combine straightening, color and conditioning?

The product integrates a relaxer base with color pigments and moisturizing agents so you treat three needs in one salon-style step. Rather than layering separate treatments, this system aims to align hair fibers, deposit Diamond Black pigment and infuse conditioning ingredients simultaneously.

• Smoothing agents reform hair alignment for reduced curl and frizz.
• Diamond Black pigments deposit even, dark color while processing.
• Built-in conditioners add slip and shine to leave hair soft.
• No peroxide or ammonia minimizes some harsh chemical sensations.

Is this relaxer safe for different hair types and textures?

The formula is described as suitable for many hair types, offering strength and body to fine, medium or coarse strands. As with any chemical straightener, results depend on hair porosity, previous chemical history and application technique; a strand test and following the instructions are important.

• Works on a wide range of natural curl patterns when applied per directions.
• Provides added body for finer hair and smoothing for coarser textures.
• Strand tests help anticipate timing and final shade on chemically altered hair.
• Scalp-safe formulation claims to avoid staining when applied properly.

What should you expect in terms of color result and shine?

Diamond Black pigment produces a deep, uniform dark shade while conditioning elements promote reflective shine and bounce. Expect a rich black tone with enhanced gloss immediately after neutralizing and styling, though final appearance can vary with starting color.

• Deep black deposition aims for consistent coverage on virgin hair.
• Conditioning agents smooth cuticles to increase surface shine.
• Neutralizing step is key to lock color and restore pH balance for lasting gloss.
• Color intensity may be lighter on pre-lightened or damaged hair.

How should this product be used for best results and safety?

Follow the included directions exactly: perform a sensitivity test, work on clean, dry hair, time processing carefully and neutralize thoroughly. Proper protective measures—gloves, ventilation and avoiding contact with eyes—will reduce risk and improve the finish.

• Always do a patch and strand test before full application.
• Apply to dry, unwashed hair for even relaxer action unless instructions specify otherwise.
• Monitor processing time closely to avoid over-processing.
• Rinse and neutralize completely, then condition to lock in moisture and color.

Who is this for: Luster Shortlooks Color Relaxer 3-n-1 Diamond Black is suited for individuals seeking a combined straightening and coloring treatment with added conditioning, especially those who want a deep black shade without using peroxide or ammonia. It’s popular for at-home stylists and professionals who prefer a single-step approach, but anyone considering chemical hair alteration should perform tests and follow safety guidelines or consult a professional for complex hair histories.
