I dyed my hair last Monday, and I used a bottle of Schwarzkopf 3% developer that my ex's mother bought for me about 2 years ago. Now I am finding that the dye is STILL rinsing out when I wash, or put it in any sort of water. I expect a little bit of wash off for the washes 2-3 times after, but this is still running off dark.
Is it possible that my developer has gone bad? I didn't see an expiry date on it anywhere, but it is possible that I missed it somehow. I did use it successfully in June however. Should I redye with a new bottle of developer in a week or so?
- Developer expiring?
