Washing hair often, whether from the gym, humidity, or a fine-hair routine that gets oily fast, adds up to a lot of shower time if every wash means shampoo, then a separate conditioner. A 2-in-1 formula combines both into a single bottle, cutting a step without necessarily cutting results.
How we choose
The eight picks below are all genuine single-bottle formulas, not a shampoo and conditioner sold as a matching two-bottle set, and every one is priced for regular drugstore restocking. A couple lean into a specific job, like treating dandruff or styling short hair, while the rest are straightforward daily options.
Our 8 Picks
Pantene Pro-V 2 in 1 Shampoo & Conditioner, Sheer Volume with Collagen, 12.6 Ounce
What it is
A 2-in-1 shampoo and conditioner from Pantene's Sheer Volume line, sold in a single 12.6-ounce bottle.
Why it's worth it
Built around Pantene's Pro-V formula with antioxidants, positioned for volume and lift rather than general moisture. Pantene designs the volumizing effect to work as a system together with its separate Volume Body Boosting Mousse, so the lift comes from pairing the two rather than the shampoo and conditioner alone. It's gentle enough for chemically treated hair, per Pantene's own description.
Caveat
The advertised volume and lift is specifically tied to using it alongside Pantene's Volume Body Boosting Mousse, so results from the 2-in-1 by itself may be more modest.
Pantene Pro-V 2 in 1 Shampoo & Conditioner, Repair & Protect with Keratin, 12.6 Ounce
What it is
A 2-in-1 shampoo and conditioner from Pantene's Repair & Protect line with keratin, sold in a 12.6-ounce bottle.
Why it's worth it
Well suited to chemically treated or heat-damaged hair, since Pantene positions this specifically for repair rather than general daily cleansing. The dual-polymer formula is built around antioxidants, which Pantene states helps prevent protein loss. A good fit for anyone who wants a single bottle aimed at damage control rather than a general all-purpose 2-in-1.
Caveat
It's formulated for repair rather than volume or color-specific care, so hair without noticeable damage may not need this particular formula over a gentler daily option.
Herbal Essences Hello Hydration 2-in-1 Shampoo Conditioner, 29.2 Fl Oz
What it is
A 2-in-1 shampoo and conditioner from Herbal Essences' Hello Hydration line, sold in a 29.2 fl oz bottle with a coconut scent.
Why it's worth it
A good fit for anyone who washes often and wants a single large bottle rather than restocking a smaller one every few weeks. Herbal Essences states the formula is paraben-free, mineral-oil-free and dermatologist-tested, and it's certified cruelty-free by PETA. Suited to color-treated hair, since the brand describes it as color-safe and pH-balanced.
Caveat
At 29.2 fl oz it's one of the largest bottles here, which is good value per wash but a bigger size to store than the smaller single-use bottles in this lineup.
Garnier Fructis Fortifying 2-in-1 Shampoo and Conditioner, 22 Fl Oz, 2 Count
What it is
A 2-in-1 shampoo and conditioner from Garnier Fructis, sold as two 22 fl oz bottles of the same formula.
Why it's worth it
Well suited to gym-goers who wash daily, since it's sold as two full-size bottles rather than one, cutting down on how often you need to reorder. Garnier states the formula is infused with grapefruit and vitamins B3 and B6, and the bottles (excluding pumps and caps) are made from 100% recycled plastic. It's Leaping Bunny certified cruelty-free and vegan, per the brand.
Caveat
Buying two bottles at once costs more upfront than a single-bottle pick, even though the per-wash cost works out lower.
Suave Anti Dandruff 2 in 1 Shampoo & Conditioner, Classic Clean, 12.6 Fl Oz
What it is
A 2-in-1 anti-dandruff shampoo and conditioner from Suave with 1% pyrithione zinc, sold in a 12.6 fl oz bottle.
Why it's worth it
A good fit for anyone managing dandruff or an itchy scalp who still wants a one-step wash, since this is the only pick here built around a dandruff-treatment active ingredient rather than general cleansing. Suave states the dermatologist-tested formula is meant for gentle daily use. It's the least expensive pick in this lineup, at under $4.
Caveat
It's formulated specifically to treat dandruff, so anyone without flaking or scalp irritation may not need the medicated formula over a standard 2-in-1.
Suave Professionals 2 In 1 Shampoo and Conditioner Vitamin Infusion, 12.6 Ounce
What it is
A 2-in-1 shampoo and conditioner from Suave Professionals infused with vitamins E, C and B5, sold in a 12.6-ounce bottle.
Why it's worth it
Suited to anyone who wants a straightforward daily 2-in-1 without a medicated or specialty formula, since this is Suave's general vitamin-infused option rather than the anti-dandruff version in this lineup. Suave states the formula is designed to boost shine and add strength to stressed hair. A budget-friendly option for frequent washing.
Caveat
Suave doesn't specify the formula for a particular hair type or concern beyond general shine and strength, so it's a generalist pick rather than one built for a specific issue.
Dove Love Your Chic Edge Short and Sweet Sulfate-Free Shampoo + Conditioner + In-Shower Styler
What it is
A shampoo and conditioner combined with a styling function, from Dove's Love Your Chic Edge line, formulated for short hair.
Why it's worth it
Well suited to anyone with short hair who wants to wash and condition in one step, since Dove markets this specifically for that hair length rather than as a general all-lengths formula. Beyond the shampoo-and-conditioner function, it also includes an in-shower memory styler meant to help mold the style as you rinse. It's sulfate-free, per Dove.
Caveat
It's formulated specifically for short hair, so it isn't the right pick for anyone with medium or long hair looking for a standard 2-in-1.
Alberto VO5 2 in 1 Shampoo & Conditioner, Deeply Nourishing, 15 Oz
What it is
A 2-in-1 shampoo and conditioner from Alberto VO5 with soy milk protein, sold in a 15-ounce bottle.
Why it's worth it
An affordable option built around soy milk protein rather than the vitamin-oil blend used in the brand's original Power of Five formula. VO5 states the formula is sulfate-, paraben- and alcohol-free. A good fit for anyone testing whether a 2-in-1 routine works for them before spending more.
Caveat
At 15 ounces it's a smaller bottle than several of the multi-pack or oversized picks in this lineup, so frequent washers may go through it faster.

Takeaway
A 2-in-1 won't replace a dedicated shampoo-and-conditioner routine for every hair type, but for busy wash days it trims a step without adding much cost. Match a general formula to daily washing, and save the dandruff or short-hair-specific picks for when your routine actually calls for them.
