Can I leave One Condition Original in my hair?
Its directions say to apply to wet curls and rinse. DevaCurl points users seeking a leave-in product to Leave-In Decadence, a different conditioner; follow the directions on your own bottle.
DevaCurl production marks and product dates
DevaCurl's No-Poo Original is a non-lathering cleanser, Low-Poo Original produces light lather, and One Condition Original is a rinse-out conditioner. These names describe different curl-care formulas, so retain the full name when recording a bottle's production mark.
DevaCurl FAQ
What does DevaCurl's 90-day stability test mean for shelf life?
That number describes a laboratory testing period under varied environmental conditions. It is not an unopened shelf life or a period-after-opening instruction for your bottle.
Does a date check cover the towel supplied with a DevaCurl set?
A DevaTowel is an accessory, not a cosmetic formula. Its care label is separate from the batch, date and opening information on the cleanser or conditioner supplied with it.
Match the DevaCurl batch to the cleanser or conditioner
Before you rely on the decoded date
- No-Poo Original is designed not to foam. Its lack of bubbles alone does not show that the bottle has expired; massage the cleanser into the scalp and rinse thoroughly as directed.
- The OG Kit combines No-Poo Original, One Condition Original and Styling Cream in separate 3 oz containers. Keep each item's lot and opening date with that item, rather than assigning the kit's purchase date to all three as a manufacturing date.
Common lookup mistakes
- Copy the complete manufacturing mark without appending the product's retail UPC or volume. Keep a photo of the front label so Original, Delight and Decadence products remain distinguishable.
- If a product causes scalp discomfort, stop using it. Contact a doctor or dermatologist if symptoms persist; an apparently recent production date is not a reason to continue using a product that causes a reaction.
