Everist is running the 20% off code for deep conditioning concentrate at the top of this page, which works best when that product is your main purchase. For shoppers buying across other products or looking for broader savings, the sitewide discounts and sale prices offer better value depending on your basket size and what you're buying.
Buying the deep conditioning concentrate alone. The 20% off code is your best bet here. Since it applies only to that product and cannot be combined with other offers, compare it to the 10% sitewide codes and any active sale price on the same item. The 20% code will win on this specific product.
Shopping across multiple items with no sale items. The 10% sitewide codes (offered several times on this page) apply to your whole order and beat the deep conditioning concentrate code when you're buying other products too. Pick whichever of the three 10% sitewide codes works best for your circumstances, all three offer the same discount but may have different access conditions depending on where you're shopping.
Buying sale products or bundles. The sale section has several strong options. The summer sale and the three bestsellers deal both offer 30% off selected hair, scalp, and skin bundles. If you find the specific bundle or item you want in the sale, these beat the 10% sitewide codes by a significant margin. On a $100 sale bundle reduced to $70 by the 30% sale price, for example, you save $30, compared to $10 with the sitewide 10% code. The hair and scalp wellness bundles also have a 25% off option and the general sale products section goes up to 30% off, so browse what's marked down and pick the highest percentage on your items. The EverBoost scalp serum trio is specifically discounted 20% in its own sale.
Buying the Shower Essentials Travel Kit. This item has its own 23% off sale deal. Take that over the sitewide 10% codes.
Getting a free product with purchase. The free charcoal konjac with an exfoliating body wash purchase adds value on top of any percentage discount you might get. Check whether a sitewide code or a sale price applies to the body wash itself before you buy.
Choosing between offers on the same items. Each code or sale deal cannot be combined with others, so on any single item, take whichever gives the largest saving. Calculate the final price under each option to be sure: a 30% sale markdown usually beats a 20% code or a 10% sitewide discount, but always check the specific item's sale price tag against the discount the code would give.
