Add a UV absorber.

@Asad_Nazir Did the pH of your product remain the same after those 3 months? Or did it drop?

What is its solution?Did you neutralize LABSA to pH 7 before adding all the other ingredients?

@Asad_Nazir It might be possible that you have an excess of NaOH, and that makes the dye degrade. You could try with a different dye (Liquitint or Hostatin type) or neutralizing with TEA instead of NaOH.
