Shopping Tips for Prime Big Deal Days
- Think winter first. The products that matter most going into fall and winter are treatments and moisture products. Prioritize those over styling staples.
- Stock up on staples. If you use it every wash day, buy 2-3. You'll use them anyway and the next big sale won't come until Black Friday.
- Prioritize the expensive stuff. A 20% discount on a $30 Olaplex saves you more than 20% off a $6 Cantu. Focus your budget on products that rarely go on sale.
- Check for clip coupons. Many products have an additional coupon on the listing that stacks with the event discount. Always check before adding to cart.
- Tools are the best investment. A Denman brush or diffuser lasts years. The savings compound over every use.
- Don't buy something just because it's on sale. Stick to products that work for your curl type. A deal is only a deal if the product actually works for your hair.
