Short answer: A good men's shampoo and conditioner is a matched pair: a shampoo that cleans your scalp and a conditioner that softens the lengths, both chosen for your hair type. Sulfate-free is a preference, not a rule, so read the label, match the formula to your scalp, and wash as often as your hair type calls for.
Open the shampoo aisle at Shoppers or Walmart and many men's options come down to one idea: a 2-in-1 that saves you a step in the shower. It does save a step. But one formula has to cleanse and condition at the same time, which is why some men with dry, curly or long hair prefer a separate shampoo and conditioner.
This guide covers what to look for in a men's shampoo and conditioner in Canada: sulfate-free versus sulfate, scalp and hair type, how to read a label and how to wash. It also covers what is in Knightsmen's rosemary shampoo and conditioner, and what the bundle costs compared with buying both bottles separately.
Key takeaways
- Shampoo cleans the scalp and conditioner softens and detangles the lengths. A 2-in-1 saves a step, while two products give you more control.
- Sulfates make shampoo foam and remove oil well, and some people find them drying. Sulfate-free shampoos clean with other agents and lather less.
- How often to wash depends on your hair. The American Academy of Dermatology says daily can suit straight hair with an oily scalp, while dry, curly or thick hair can go longer.
- Read the ingredient list: the cleansing agents near the top, where the scent comes from, the preservative, and anything you know you react to.
- Knightsmen's rosemary shampoo and conditioner are sulfate-free and made with organic ingredients, scented with rosemary and tea tree oils, and the bundle costs less than the two bottles bought separately.

Should I choose a sulfate-free shampoo?
It is a preference more than a rule. Sulfates, such as sodium lauryl sulfate and sodium laureth sulfate, are the cleansing agents that give many shampoos their big lather, and they remove oil and product buildup well. Some people find them drying or irritating on the scalp, especially when it is dry or sensitive. Others use them without any trouble.
Sulfate-free shampoos clean with other agents, such as decyl glucoside and cocamidopropyl betaine. They usually lather less, but a lighter lather is a difference in texture and does not by itself mean the shampoo cleans less. If your scalp is very oily or you use a lot of styling product, a sulfate shampoo may suit you. If your scalp is dry or sensitive, a sulfate-free one is worth trying.
Either way, a "sulfate-free" label only tells you what a shampoo leaves out. Read the whole ingredient list to see what is in it.
How do I choose a shampoo for my scalp and hair type?
Start with two questions: how oily does your scalp get, and how does your hair behave once it is dry? The American Academy of Dermatology says how often to shampoo depends on your hair type:
| Your hair and scalp | How often to shampoo | Where to put conditioner |
|---|---|---|
| Straight hair with an oily scalp | You may want to shampoo every day | On the ends for fine or straight hair |
| Dry, textured, curly or thick hair | When needed, at least once every 2 to 3 weeks | On the whole length for dry or curly hair |
| Our rosemary shampoo and conditioner (our directions) | 3 to 5 times a week | After shampooing; leave in for 2 to 3 minutes |
If you fall between the first two rows, go by how your scalp and hair feel: shampoo when your scalp feels oily or dirty, and add more conditioner if your hair feels dry. Apply shampoo to the scalp rather than the whole length of the hair, as the AAD advises. That removes oil and product buildup from the scalp without drying out the lengths.
How do I read a shampoo or conditioner label?
In Canada, cosmetic ingredients are listed in descending order of concentration, with ingredients at 1% or less allowed in any order, according to Health Canada's labelling guide. Water comes first in most shampoos, so look at what follows:
- Cleansing agents. Sodium lauryl sulfate or sodium laureth sulfate means a sulfate shampoo. Names such as decyl glucoside or cocamidopropyl betaine are common in sulfate-free shampoos, but check that no sulfate is also listed.
- The scent. Essential oils are listed by plant name, for example Rosmarinus Officinalis for rosemary. "Parfum" can stand for a blend of scent ingredients that are not named one by one, so choose a fragrance-free shampoo if scent bothers you.
- The preservative. Water-based products such as shampoo and conditioner need one to keep them from spoiling. Our shampoo and conditioner use phenoxyethanol. Avoid any ingredient you know you react to.
- Conditioning ingredients. In a conditioner, look for plant butters and oils such as shea butter and argan oil, and fatty alcohols such as cetyl alcohol, which give it a creamy feel.
- Front-of-bottle words. "Natural" and "clean" do not tell you what is inside, and even natural ingredients can cause a reaction in some people. The list on the back does.
What is in Knightsmen's rosemary shampoo and conditioner?
Both are sulfate-free and paraben-free, made with organic ingredients, and handcrafted in small batches in Toronto. Rosemary and tea tree oils run through both. Here is what else is in them:
- Rosemary oil: a traditional hair-care ingredient. It is often discussed online as a hair-growth ingredient, but research is limited and mostly small or in animals, and it is not a medical treatment. We include it for its scent and its place in traditional hair care; see our rosemary oil guide.
- Tea tree oil: adds a fresh, clean scent.
- Cedarwood and jojoba oil (shampoo): cedarwood adds a clean, woodsy scent that does not read as synthetic fragrance, and jojoba is a plant oil often described as similar to the skin's own oils.
- Shea butter and argan oil (conditioner): organic plant butter and oil that soften, hydrate and detangle.
- The cleansers: a sulfate-free wash base built from coconut- and plant-sugar-derived cleansing agents.
We describe them as cosmetics that help promote healthy hair growth as part of a routine. They cleanse, condition and scent, and they do not replace medical care. They are scented with essential oils, so they are not the pick if you want a fragrance-free shampoo.
Is the shampoo and conditioner bundle cheaper than buying them separately?
Yes. At the time of writing, the shampoo is $53 and the conditioner is $57, so $110 together (prices in CAD). The bundle is $95, which saves $15. Each bottle is 8 fl. oz (237 ml).

How do I use shampoo and conditioner correctly?
Shampoo the scalp, rinse thoroughly, then condition the lengths. Good technique takes no extra time.
- Wet your hair thoroughly with lukewarm water.
- Apply the shampoo to your scalp, not the whole length of the hair, and massage it in with your fingertips for 2 to 3 minutes, as our directions say. Then rinse thoroughly so no product is left behind.
- Apply the conditioner after shampooing. Put it on the ends if your hair is fine or straight, or on the whole length if it is dry or curly, and leave it in for 2 to 3 minutes before rinsing.
- Dry gently. The AAD advises wrapping your hair in a towel or T-shirt to absorb moisture, because rubbing it dry roughly can damage it.
- Match the frequency to your hair. Our directions suggest using the shampoo 3 to 5 times a week; the table above shows the AAD's guidance by hair type.
Shampoo and conditioner change how your hair feels, looks and behaves day to day. They do not change how much hair you have, so see a doctor or dermatologist about sudden shedding or thinning.

Frequently asked questions
How often should I wash my hair?
It depends on your hair type. The American Academy of Dermatology says you may want to shampoo every day if you have straight hair and an oily scalp, and when needed, at least once every 2 to 3 weeks, if your hair is dry, textured, curly or thick. Our directions for the rosemary shampoo suggest 3 to 5 times a week. Beard skin is different: the AAD advises washing your face and beard every day with a gentle cleanser rather than soap. See our beard washing guide.
Is sulfate-free shampoo actually better?
It depends on your scalp. Sulfates clean oil and buildup well, and some people find them drying or irritating, so a sulfate-free shampoo is worth trying if your scalp is dry or sensitive. If your scalp is very oily, you may prefer the bigger lather of a sulfate shampoo. Sulfate-free formulas clean with other agents such as decyl glucoside and lather less, which is a difference in texture.
Can women use this too?
Yes. The formulas are not gender-specific. They are sold in a men's grooming range, but anyone who likes the scent and the sulfate-free base can use them. They are scented with essential oils, so choose a fragrance-free shampoo if you prefer no scent.
Is the rosemary shampoo a dandruff shampoo?
No. Knightsmen's rosemary shampoo is a cosmetic cleanser, not a dandruff treatment. The AAD notes that flakes can come from not shampooing often enough or from using the wrong products for your hair type. If flakes or itching persist, see a doctor or dermatologist, who can tell what is behind them and recommend what suits you.
How long before I notice a difference?
You will notice how it cleans, lathers, smells and feels from the first wash. Shampoo and conditioner change how hair feels and looks, not how much hair you have, so there is no set timeline for change. If you are worried about shedding or thinning, see a doctor or dermatologist.
Do I need to buy the shampoo and conditioner together?
No. They are designed as a pair, with the shampoo cleaning and the conditioner softening and detangling, but each is sold on its own. If you already like a conditioner, the shampoo stands fine alone, and the same goes in reverse for the conditioner. The bundle costs less if you need both.
