4n hair color

4N denotes a level‑4 natural brown — a medium to deep natural brown shade. Product labels may use phrases like “Medium Intense Natural Brown,” “Deep Brown,” or “Natural Dark Brown” to describe this tone.

Processing times vary by formula. Many permanent 4N creams list about 25–35 minutes; some express formulas process in ~10 minutes and others require up to 35 minutes. Always follow the product’s instructions and perform a strand test if unsure.

Kits commonly include the color cream and developer plus a conditioning product; some kits use multiple pre‑measured pouches for precise dosing and may include applicator tools (tray, comb) or protective items. Packaging formats vary — check the box for exact contents.

Listed sizes range from small treatment bottles (about 1.7 oz) up to cream tubes or kits around 2.05–3.4 oz. Examples found include 1.7 oz, 2.05 oz, 2.12 oz, and 3.4 oz; actual sizes depend on the product type.

Many 4N color products are labeled for all hair types. Some listings specifically note suitability for curly or color‑treated hair. Treatment oils and toners are often marketed toward blonde, highlighted, or silver hair that needs toning and added moisture.
