Schwarzkopf IGORA ROYAL Permanent Color Creme (4-0 Medium

Schwarzkopf IGORA ROYAL 4-0 Medium Brown is a professional permanent hair color creme that delivers even, long-lasting medium brown results with rich pigment and reliable grey coverage when mixed and applied per instructions.

IGORA ROYAL is a salon-grade permanent hair color line from Schwarzkopf Professional designed for stylists and experienced home users who follow professional mixing ratios. The 4-0 shade (Medium Brown) provides a natural, neutral brown tone formulated to deposit intense color, balance reflect, and cover up to 100% grey hair in many cases. It’s formulated to work with developers at recommended volumes for predictable lift and deposit.

How does IGORA ROYAL 4-0 achieve consistent medium brown results?

The creme pigment system in IGORA ROYAL is engineered to deliver uniform color distribution across the hair shaft. When used with the correct developer and application technique, the pigments penetrate evenly to produce a stable medium brown shade with balanced warmth and depth.

• Professional-level pigment blend for balanced medium brown tone
• Creme texture helps with even application and reduced dripping
• Works with standard 10/20/30/40 volume developers depending on desired lift
• Formulation supports predictable color repeatability session-to-session

What coverage and lift can I expect from shade 4-0?

Shade 4-0 is a natural medium brown with strong depositing power, designed mainly to cover grey and darken or refresh natural brown hair. Expect up to full grey coverage on most hair types if application follows product directions; it’s not intended for large lifts from very light bases without prior lightening.

• Full coverage for up to 100% grey depending on hair condition
• Best used to maintain, deepen, or refresh medium brown bases
• Limited lift—pre-lightening required for significant lightening
• Developer choice affects depth, tone, and deposit intensity

How should I mix and apply this permanent color creme safely?

Follow Schwarzkopf Professional’s mixing instructions and safety guidance: use the recommended developer volume, perform a patch/strand test, wear gloves, and avoid contact with eyes. Apply to dry hair for standard retouch or to roots-first for re-coloring, then process for the instructed time to achieve the intended shade.

• Mix with the recommended IGORA developer at specified ratio
• Perform allergy patch and strand tests 48 hours before use
• Apply to clean, dry hair; root application followed by mid-lengths/ends
• Rinse, shampoo, and condition per Schwarzkopf aftercare instructions

What aftercare keeps the 4-0 medium brown looking fresh longer?

Use color-safe shampoos and conditioners, minimize heat exposure, and protect hair from UV and chlorinated water to preserve color depth and shine. Professional color care treatments from Schwarzkopf help maintain pigment integrity and reduce premature fading between salon visits.

• Shampoo and conditioner formulated for color-treated hair
• Use heat protection sprays when styling with hot tools
• Limit sun and chlorine exposure, or use protective products
• Regular gloss or tone refresh appointments for lasting vibrancy

Who is this for: Schwarzkopf IGORA ROYAL 4-0 Medium Brown is aimed at professional stylists and knowledgeable home users who want a dependable permanent medium brown shade with strong pigment and grey coverage. It’s ideal for refreshing natural brown hair, darkening lighter tones, or covering greys when paired with the appropriate developer and professional application techniques. If you require major lightening or have specific hair damage concerns, consult a professional colorist before use.
