Quick answer: Use shampoo primarily on the scalp, where sebum, sweat, dead cells, and styling product residue accumulate. Apply conditioner after rinsing shampoo, mainly to the lengths and ends of the hair. It helps to hydrate, detangle, and better protect hair from breakage. For fine or straight hair, focus on the ends; for dry or curly hair, you can treat the entire lengths as needed.

Shampoo and conditioner have different tasks
Imagine hair care in two steps. The first step cleans the area where impurities originate. The second cares for the hair fiber, which is exposed to friction, heat, sun, and styling along its entire length.
- Shampoo primarily cleans the scalp and roots.
- Conditioner facilitates detangling, improves manageability, and helps protect the lengths from mechanical damage.
Therefore, conditioner is not "an unnecessary extra shampoo." It complements the effect of washing where cleaning alone is not enough.
What exactly shampoo does
Sebum is naturally produced on the scalp. It mixes with sweat, dust, dead cells, and styling product residues. Shampoo helps to loosen this mixture and remove it during rinsing.
The American Academy of Dermatology recommends applying shampoo mainly to the scalp, not scrubbing the entire length. The lather that runs down the hair during rinsing is usually sufficient to clean the lengths and does not unnecessarily dry them out.
How often to use shampoo depends on how quickly your scalp gets oily and your hair type. Straight hair with an oilier scalp may need more frequent washing. Dry, thick, or curly hair is usually washed less often. Don't follow a universal number of days – observe the condition of your scalp and hair.
What conditioner is for
Wet hair is more sensitive to pulling and friction. Conditioner coats the hair fibers, gives them slipperiness, and makes detangling easier. Dermatologists state that regular conditioner can help reduce breakage, split ends, and frizz.
After using conditioner, hair tends to be:
- softer and more pliable,
- easier to detangle,
- less prone to tangling,
- smoother to the touch,
- better protected from damage during combing.
However, conditioner cannot permanently "repair" an already split end. It can temporarily smooth its surface and reduce further friction, but a truly split part needs to be trimmed.
Correct order: shampoo then conditioner
1. Wet hair thoroughly
Lukewarm water helps distribute the shampoo evenly. Very hot water can unnecessarily dry out the scalp and hair.
2. Apply shampoo to the roots
Spread a small amount between your palms and gently massage it into the scalp with your fingertips. Do not scratch with nails or rub the lengths together. Rinse the shampoo thoroughly.
A second wash is not automatically necessary. It may make sense with significant styling product build-up, a very oily scalp, or if recommended by the product manufacturer.
3. Gently squeeze water from the lengths
Hair doesn't have to be dripping. On completely saturated hair, the conditioner will be unnecessarily diluted and will run off more easily.
4. Apply conditioner to the lengths and ends
Start with a small amount and add more only as needed. For fine and straight hair, focus on the ends. For dry, thick, or curly hair, conditioner can be spread throughout the entire length, but usually still away from the scalp.
Leave on for the time indicated on the packaging. Longer application may not yield better results.
5. Rinse and handle hair gently
Rinse the conditioner according to the manufacturer's instructions. Do not rub hair with a towel. Gently squeeze out excess water and wrap it in a soft towel or t-shirt. Carefully detangle wet hair with a wide-tooth comb.
Where to apply conditioner according to hair type
| Hair type | Recommended focus |
|---|---|
| Fine or straight | small amount primarily on the ends |
| Normal | from mid-lengths to ends |
| Dry, thick, or curly | as needed throughout the lengths, thoroughly on the ends |
| Quickly greasy at the roots | avoid the scalp and treat only dry lengths |
| Color-treated or heat-damaged | gentle shampoo and regular conditioner according to manufacturer's recommendations |
These are general guidelines, not a diagnosis. If a product weighs down your hair, reduce the amount or choose a lighter formula. If your lengths are still dry and tangled, a richer conditioner may help.
How much to use
An exact universal dose cannot be determined, as length, density, texture, and product concentration all play a role. Start with a small amount and spread it evenly. You can always add more, but you can't remove excess product.
Too much shampoo can unnecessarily dry out hair and be wasteful. Too much conditioner can weigh down fine hair or leave a greasy feeling at the roots. Always follow the label of the specific product.
Is a 2-in-1 product the same as shampoo with conditioner?
Not always. The "2-in-1" label can mean different combinations. For example, Botanica Shampoo for Hair and Body, 360 ml combines shampoo and shower gel – it's not a shampoo with conditioner.
If the lengths need easier detangling and greater manageability after washing, supplement it with a separate Botanica Hair Conditioner, 360 ml. For hotels, wellness centers, or facilities with higher consumption, both products are also available in five-liter packaging: shampoo for hair and body 5 l and hair conditioner 5 l. What the claims on the packaging of these products mean is discussed in the article what does biodegradable mean.
Common hair washing mistakes
- Shampoo along the entire length: repeated scrubbing can especially dry out the ends.
- Conditioner to the roots of fine hair: the hairstyle can quickly lose volume and appear greasy.
- Too large a dose: more product does not automatically mean better care.
- Insufficient rinsing: residue can weigh down hair and irritate the scalp.
- Rough towel rubbing: wet hair is more prone to damage.
- Too hot blow-drying: high temperatures can further stress the hair fiber.
Frequently asked questions
Do I have to use conditioner after every shampoo?
The American Academy of Dermatology recommends conditioner after washing. However, adjust the amount and type to your hair. Fine hair may only need a small amount on the ends, while dry and curly hair usually benefits from a more thorough treatment of the lengths.
Does conditioner make hair greasy?
Properly chosen and dosed conditioner should not make the lengths greasy. The feeling of heavy hair often arises from too large a dose, insufficient rinsing, or application to the roots.
Can conditioner stop hair loss?
Conditioner can reduce breakage caused by friction, but it does not treat the causes of hair loss from the roots. If you experience sudden or significant hair loss, itching, pain, or skin changes, consult a dermatologist.
How long should I leave conditioner on?
Exactly according to the label. A regular rinse-out conditioner may only need a short time, a mask usually longer. Longer application itself does not guarantee a better effect.
Should shampoo go on the scalp or the hair?
Primarily on the scalp and at the roots. During rinsing, the lather flows over the lengths and removes common impurities without unnecessary scrubbing.
A simple duo for balanced care
Shampoo removes impurities where they accumulate most, and conditioner helps protect the parts of the hair that are oldest and most stressed. The correct procedure is therefore simple: shampoo at the roots, conditioner on the lengths, and both in an amount appropriate for your hair type.
