Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
I love this product because it moisturizes my baby hair soo well and has a lovely and welcoming scent that lasts for days even after rinsing her hair. I also noticed hair growth at the bald spot usually at the back of a baby's head. I just wished the price was lesser given the size of the product.
