According to top hairstylists, adding a second shampoo to your shower routine is one of the best ways to achieve fantastic locks. Speaking to The Independent, hairstylist Ian Florey raves about the benefits of shampooing your hair twice. 'The hair will become a lot stronger, shinier and healthier,' he told them.
Wash your hair three times a week with the 2-in-1 Shampoo/Conditioner, which is a nice balance of cleaning power and moisture so you don't end up frizzing out.
“Shampooing your hair twice is beneficial because it allows for proper cleansing, giving you longer periods of time with a clean scalp and keeping away the oily hair problem,” he says. “It also keeps you away from over-shampooing your hair, which is a mistake that most women make.”
"The only downside to using a 2-in-1 is that the hair can begin to feel heavy over time," says Cardona. "Occasionally alternating to a clarifying or exfoliating shampoo rather than a conditioning shampoo will let you reap all the benefits of silicones without the unwanted buildup."
The advantages of using a 2-in-1 are aplenty — first off, there's the time-saving, one-stop-shop aspect of it all. "A 2-in-1 still moisturizes and cleanses your hair, but saves you time by not having to do the two separate steps in the shower," says Jana Rago, a hairstylist and owner of Jana Rago Studios.
The final verdict? Conditioning-shampoos can be better than two separate bottles if you're showering every day or have curly or brittle hair. If you have thin or oily hair, though, stick to your separate shampoo and conditioner bottles and opt for a lighter formula that won't weigh your strands down.
Shampoos labeled as 3-in-1 are often criticized for not being particularly effective in any one capacity: The shampoo is not strong enough to treat extremely dry or oily hair, the conditioner doesn't stay effective long enough, and the body wash provides minimal fragrance.
If you want to remove all of that build up and achieve squeaky clean strands, one lather might not be enough. That's where double shampooing comes in. The first round essentially rids build up and residue from the hair, while the second will actually cleanse and nourish your strands.
Mixing shampoos will definitely not make all your hair fall out, says cosmetic chemist Ni'Kita Wilson, but there are some beauty products that when combined do more harm than good. Avoid mixing AHAs (alpha hydroxy acids, which exfoliate) with retinol products.
Bottom Line Despite what you may have heard, 2-in-1 shampoos do not damage hair or coat hair with layers of wax or plastic. In fact, most moisturizing and conditioning shampoos use 2-in-1 technology (even if it doesn't say 2-in-1 on the label). The truth is, these products work and they work well.
A 2-in-1 shampoo is designed specifically to deliver the cleansing benefits of a traditional shampoo while providing the moisturizing benefits of a conditioner, eliminating the need to use two separate products.
If you're Mr. Multitasker and believe even your grooming products should do two jobs at once, then yes, a shampoo/conditioner may be worth trying. When you suds up your scalp with a 2-in-1, cleansing agents called surfactants bind to the dirt and excess oil in your hair, and pull them off as you rinse.
You may use shampoo and conditioner back to back but ensure your shampoo is rinsed out prior to applying your conditioner if you are looking for the best results. Due to the two separate jobs your shampoo and conditioner serve, you will want to avoid using them at exactly the same time.
Some hair stylists swear by double shampooing, suggesting that the first shampoo helps remove dirt and oil and the second shampoo helps impart nourishing benefits.
"Double shampooing is usually absolutely fine for all hair types – I would say it is more down to the type of shampoo you are using," Adam explains. "If you have colour treated hair, make sure you are using a shampoo that protects the colour in-between salon appointments."
You actually SHOULD shampoo twice if you color your hair.
But actually, doing a repeat will help your color look more vibrant by removing dirt and oils, which can darken your mane. The first wash tends to mix up all the dirt; the second shampooing really removes them.
4-5 times a week, depending on how dirty your hair gets.
Similar to its skin counterpart, hair double cleansing involves shampooing twice. The first go-around is intended to remove heavy product buildup, dirt, and natural oils. The second shampoo is supposed to finish the job and give you a clean canvas for styling.
Using both a clarifying and moisturizing shampoo can help cleanse your scalp and keep your curls hydrated and shiny. You can shampoo your hair once or twice depending on your preference, follow up with a moisturizing shampoo, and proceed with your usual conditioning or deep conditioning session.
Shampoo often strips the natural oils from the hair and putting 2 applications of shampoo on will do more harm than good. If you want the benefits of both shampoos, it's better to wash one day with one, then about 2 days later when you wash your hair again, use the other one. And always follow with a good conditioner.
You'll get the volumizing benefits of shampoo with much of the moisture-drenching impact of co-washing. Giving your curls a double condition should trigger reduced frizz, more shine, and softer spirals.
