Kaya Skin Clinic's Hair Gel & Hair nourishing shampoo
The products have no expiry date/period mentioned on it

I bought the above mentioned products from their clinic based at Sion, Mumbai on 06th Sept '2009. The hair gel had the mfg dt as 12 & shampoo as 07 but there was no expiry mentioned on it. How can they sell without any mention of expiry.
