Give them awayI know, I know, I know. How could I give away a product that my hair hated? Just because it didn't work for me, doesn't mean it won't work for someone else. There are several people in my life between family and friends who aren't as selective about what they use on their hair like I am. And if it's free...yes please!
I've also given away some products to Goodwill. This only happens when I have used the product 1-2 times so the bottle feels and looks close to full.
Mix them with other products or ingredientsIf the shampoo or conditioner wasn't so bad that it caused my hair to start a revolution, I'll use it in a mix. I'll take the shampoo and mix a little bit with a shampoo from my go-to stash. The conditioner may end up in a pre-poo mix with a conditioner my hair likes and some of my favorite oils. I've found that using more of the go-to product/ingredient in the mix helps to negate the issues experienced when using the not-working product alone.
Use the conditioner as shaving creamSome former coworkers once told me when they travel and stay at hotels they use the free conditioner for shaving cream. I was skeptical about how conditioner would work in place of shaving cream, but gave it a try and found it totally works!
Now when I have a conditioner that didn't work for my hair I may opt to keep it and use it instead of shaving cream. Conditioners that don't help my hair feel soft and moisturized can help my legs and underarms feel soft and moisturized during shaving.
Use the shampoo to clean hair toolsShampoos that I've stopped using and don't want to use in a mix are now my cleansers for combs, brushes, containers I use to mix product, and applicator bottles. I mean they are supposed to be cleansers so why not let them do what they were made to do.
Return them to the storeYep. I've done this plenty of times. If I've used a hair product once or twice and it just isn't working for me, I get the receipt and return the product for a refund. There's nothing wrong with returning it, if it's not working or you don't like it and you follow the stores return policy.
Leave them out for guestsWhen I travel and stay with family I don't always bring a lot of toiletries because I know I can "borrow" some of theirs. This could also be true for some of your family and friends who visit you. So why not place some these shampoos and conditioners you don't like in your guest bathroom for guests to use? I've done this a few times and my guests have really appreciated it.
How do you get rid of hair products that didn't work for you?
