Shampoo is okay. Thank you

This seller is dishonest and unethical in doing business by sending both hair serum with less than 4 months of expiry date! Seller is also rude and non-reponsive and insisted the items can last for 1 year as long as i open within expiry date, meaning I have to open both serum to use at the same time?! Seller also said expiration date is not expiration date?! Buyers to avoid this seller at all cost!

First time trying the shampoo. Cheaper than retail store.
