How Big Is a Liter of Shampoo and Conditioner?
A liter of shampoo and conditioner is larger than a standard size and a salon (medium) size. It is 33.8 fluid ounces or 1000 ml of product.
How Long Do Liters of Shampoo and Conditioner Last?
The answer depends on your hair length, thickness, type, and how often you wash. If you have short, fine hair, a liter can last over a year or two. Medium hair with moderate thickness will last you a year or longer. A liter for long, thick hair may last six months to a year.
Why Buy a Liter-Sized Shampoo and Conditioner?
If you’re looking for the best value and most sustainable option. Here’s why:
- They’re the best value. You might pay more upfront for a liter of shampoo and conditioner, but in the long run, they’re cost-effective, and your wallet will love you.
- They’re sustainable. Buying a liter of shampoo and conditioner instead of multiple smaller bottles reduces plastic waste.
- You stick to what’s known to work. If you buy a liter-sized shampoo or conditioner, you get to be loyal to it. That means no more searching around and trying different products to no avail. You get a consistent routine for your hair.
Cost-Effective
A liter of shampoo or conditioner may seem costly upfront, but it saves you money in the long run. Purchasing multiple bottles of shampoo and conditioner adds up over time, exceeding the cost of a liter.
Less Waste
Although they’re bigger, liters are better for the environment. Buying a liter-size bottle of shampoo and conditioner prevents you from having to purchase multiple, smaller containers, meaning less plastic waste.
Perfect for Loyal Users
A liter size is worth the investment if you’re dedicated to a specific shampoo and conditioner. You won’t feel tempted to jump from product to product when you already have a long-lasting liter you trust.
Great for Long, Thick Hair
Longer, thicker hair calls for more product. A liter may be for you and will save you the hassle of frequently purchasing smaller bottles of shampoo and conditioner. Even if your hair is short or finer, you can still enjoy all the other benefits of liters.
Household Friendly
A liter of shampoo and conditioner is perfect if you live in a household with multiple people. These bottles can efficiently serve multiple hair types and even save space from not having multiple different shampoos and conditioners in the house.
