Review on 🧴 Neutrogena T/Sal Therapeutic Scalp Shampoo for Scalp Build-Up Control with 3% Salicylic Acid - Dandruff, Psoriasis & Seborrheic Dermatitis Relief, 4.5 fl. oz (Pack of 6) by Walter Hunter

I've been using this shampoo regularly for a number of years - it's nice and gentle on my sensitive scalp. However, I have noticed that the bottles in this shipment appear a bit underfilled compared to the bottles I recently purchased from CVS. So I used one of the bottles to fill the other 5 and found that out of the six bottles, more than half of one bottle was missing! (see photos) I don't know if this is related to Neutrogena or if the seller did something to the bottles. Unfortunately, it is not possible to say whether they were fake.
