How to grow long hair – hair growth, length retention and care

If you want long hair, it helps to separate two things: how quickly hair grows from the follicle and how well you retain the lengths you already have. A hair care routine cannot promise faster biological growth, but gentle care can help reduce unnecessary breakage.

How fast does hair grow?

For many people, scalp hair grows around 1 cm per month, although the rate varies between individuals and over time.

How much does hair grow in a month?

A useful average is roughly 1 cm per month. Some people will see a little more and others a little less.

How long does it take to grow long hair?

That depends on your starting length, your natural growth phase and how much length you retain. If the ends break frequently, hair can appear to stand still even while it is growing at the scalp.

Why length retention matters when you want long hair

When lengths and ends are exposed to friction, very high heat, chemical treatments or rough handling, strands can break. Reducing unnecessary breakage makes it easier to retain the length that grows in.

1. Take care of the lengths and ends

Use conditioning that suits your hair type and pay particular attention to dry or rough ends. Detangle from the ends and gradually work upwards.

• Detangle gently rather than pulling through knots.
• Use conditioner or suitable leave-in care for better slip.
• Trim worn or split ends when needed.

See our guide to hairbrushes for long hair.

2. Wash your hair according to your needs

There is no single wash frequency that suits everyone. Hair type, scalp, activity level and styling products all matter. Read our guide on how often to wash your hair.

3. Brush and detangle gently

Work in sections if helpful, start at the ends and move upwards. The aim is smooth hair without unnecessary pulling.

4. Limit very high heat

Repeated very high heat can leave lengths more vulnerable to dryness and breakage. Use a moderate temperature and heat protection when heat styling.

5. Reduce friction overnight

Consider wearing hair loosely secured at night and avoid very tight styles while sleeping. See our guide on how to sleep with long hair.

6. Adapt the routine to your hair type

Fine, coarse, straight, wavy and curly hair can have different needs. Choose products and techniques based on how your own hair responds.

Can you make hair grow faster?

A cosmetic hair care routine primarily affects existing strands and the scalp. It can help you care for the hair and retain length, but that is not the same as increasing the biological growth rate from the follicle.

How much does hair grow in a year?

Many people will see roughly 10–15 cm of new growth over a year, but there is substantial individual variation.

Can everyone grow very long hair?

Not necessarily. Maximum natural length is influenced by the length of the growth phase, genetics and how well the lengths are retained.

Good habits if your goal is longer hair

• Be consistent with gentle care.
• Limit rough detangling and repeated very high heat.
• Care for the lengths and ends, not only the scalp.
• Adapt washing and styling to your hair type.
• Judge progress over months rather than days.
