1. How to wash hair extensions correctly
To care for your extensions properly, you need to wash them regularly. For clip-in extensions this is enough after roughly every 10-15 uses; permanent extensions need cleaning more often. Before washing, gently detangle the hair with your fingers and brush it thoroughly from the ends up to the roots.
It is best to wash your hair extensions upright in the shower. Carefully shampoo only the scalp and let the foam run down over the lengths. A treatment on the lengths and ends (2-5 min) adds extra smoothness. Make sure conditioner never touches the attachment points!
2. No-gos in extension care
- Do not wash upside down: This leads to tangling and can damage the attachment points.
- Never rub dry: Instead, gently squeeze the hair in a towel.
- Avoid brushing while wet: Hair is particularly elastic and sensitive when wet.
3. What shampoo for hair extensions is best?
The best shampoo for hair extensions is free from silicones, alcohol and oils. These ingredients can massively impair the durability of the attachment points (tapes or bondings) and make the hair greasy at the roots. A mild, moisturising formula cleans the scalp without drying out the lengths.
Our specially formulated hair extension care range – shampoo, conditioner and hair oil – is developed to work with bonds, tapes and rings, giving both your natural hair and the extensions intensive moisture.
4. Hair extension care routine
Brush your hair thoroughly twice a day with a special extension brush. Check the attachment points every 4 weeks. If strands become loose, have them moved up promptly by a hairdresser or a friend. Read more on why extensions get dry and matted.

5. Styling with hair extensions
You can blow-dry, straighten or curl your hair extensions. Always use a medium heat setting to avoid drying out the human hair. The gentlest method is air-drying. When using styling products, make sure they contain no alcohol or oils that could attack the connections.
6. Can you dye extensions?
Synthetic hair and Standard human hair should not be dyed. For Premium human hair, colour adjustment is possible because the cuticle layer is intact. We still recommend choosing the right shade directly from our wide range of colours to protect the structure – see our guide on dyeing and bleaching extensions.
7. Sports with hair extensions
Sport is no obstacle. Always tie your hair in a braid or bun (for example a high bun with tapes) to avoid friction and matting caused by sweat. This keeps the attachment points safely protected.
8. Saltwater and chlorine
Chlorine and salt strip moisture from the hair. When swimming, it is best to pin your hair up. Should it get wet anyway: rinse immediately with fresh water and then use a nourishing hair mask to neutralise salt residues.
9. Sleeping with extensions
Tip: Never sleep with wet hair! Moisture causes the attachment points to swell and promotes matting through nightly movement.
Brush your hair thoroughly before bed and tie it into a loose braid or bun. This prevents mechanical friction on the pillow. Alternatively, a silk turban protects your hair extensions particularly gently.

Conclusion
Proper care is the key to long-lasting hair extensions. Avoid harmful ingredients like silicones and alcohol, keep heat moderate, and protect your hair at night and during sport with loose braids. Combined with the right shampoo for hair extensions, your hair2heart extensions will stay supple and shiny for months.
