Oh no, seeing a splash of hair dye on a leather sofa is a real heart-stopping moment, but don't worry! It's a common issue, and there are definitely ways to tackle it.
While one of the links you provided didn't contain specific cleaning instructions, helpful communities online often suggest a very effective method using a common household item: rubbing alcohol (isopropyl alcohol).
The most important first step, no matter what method you choose, is to test it on a small, hidden area of your sofa. This could be on the underside of a cushion or a flap on the back. This will ensure the solution doesn't discolor or damage your leather's finish.
Once you've done a successful spot test, dampen a cotton ball or a Q-tip with the rubbing alcohol. Gently dab at the hair dye stain, being careful not to rub, which could spread the stain or damage the leather. You should see the dye start to transfer onto the cotton. Keep dabbing with fresh, clean cotton balls until the stain is lifted. An alcohol-based hairspray can also work in a pinch; just spray it onto a cloth first, not directly onto the sofa, and then dab the stain.
Because alcohol is a solvent, it can dry out the leather. After the spot is clean and has fully dried, it's crucial to apply a good-quality leather conditioner to the area. This will restore moisture and help protect the finish, keeping your sofa looking its best.
