DyeCast: Hair Color Fade Guide

Color your hair at home? Track wash count against your water hardness, shampoo type, and heat routine to know when your color will fade and when to re-dye.

Stop guessing when your hair color will fade. DyeCast tracks your wash count and calculates how many washes your color has left — based on your dye type, water hardness, shampoo, heat styling, and hair porosity.

Every home colorist knows the frustration: your red fades in two weeks while your friend's lasts a month. The difference? Water hardness, shampoo choice, and heat tool usage all affect fade speed — and the math is different for everyone.

HOW IT WORKS

1. Set up your color profile: dye type (permanent, demi, semi, or temporary), shade category, water hardness, shampoo type, heat styling frequency, and hair porosity.
2. DyeCast calculates your estimated wash life — the number of washes before noticeable fading.
3. Tap "I Washed Today" each wash day. The app updates your fade status, remaining washes, and estimated re-dye date. It takes 30 seconds to set up. No account required.

FADE STATUS AT A GLANCE See your color's current fade level on a simple visual gauge. Green means fresh, yellow means fading, red means time to re-dye. Know your remaining wash count and estimated re-dye date instantly.

WASH COUNT TRACKER Log each wash with one tap. Your fade estimate updates in real time. See how your routine affects your color longevity.

WATER HARDNESS GUIDE Learn whether your tap water is soft, moderate, hard, or very hard — and how it impacts your color. Hard water can reduce color life by 30-50%.
