This page sets out the terms for using the onnahair.com website. By using the site, you are deemed to have accepted these terms. The site is operated by Onna Saç Sistemleri Sanayi ve Ticaret Ltd. Şti. (“ONNA HAIR”).
1. Nature of the information on the site
The articles, Q&A and images on the site are for information only. They do not replace medical diagnosis, treatment or advice. If you think there may be a medical cause behind your hair loss, consult a doctor. You are responsible for decisions you make based on information on the site.
2. Before and after images
The fitting photos on the site are of real clients and are published with their permission. Results vary from person to person: the degree of hair loss, scalp type, chosen system and care habits affect the result. These images do not constitute a promise of any result.
3. Appointment requests
An appointment request you send through the forms on the site is only a request; on its own it does not create an appointment or a binding contract. Your appointment is confirmed once our team confirms it with you by phone, WhatsApp or email. If you cannot attend your appointment, please let us know in advance.
4. Prices
The price ranges given on the site are for information only and are not a binding offer. The exact price for you is communicated in writing after a free consultation, depending on the chosen system, hair density, fitting area and care plan. Prices may change without notice; however, an offer communicated to you in writing remains valid for the period stated in the offer.
5. Where the service is provided
ONNA HAIR provides its services at a single centre: Esentepe Mah. Kore Şehitleri Cad. No:11/A, Şişli / Istanbul. The site contains no statement that we have any other branch; if other addresses claim to provide services on our behalf, please contact us.
6. Intellectual property
The texts, photos, videos, logo and trademarks such as “ONNA”, “ONNA HAIR”, “ONNA PRO” and “breathtec” on the site belong to ONNA HAIR or its licensors. They may not be copied, reproduced or used for commercial purposes without written permission. Short quotations with the source cited are permitted.
7. User content
You are responsible for the content you submit to the Q&A section or comment fields. We reserve the right not to publish, or to remove, posts containing insults, advertising, misleading health claims or other people's personal information.
8. Your personal data
Information you send through the forms is processed only to respond to your request. For details, see our KVKK Information Notice, Privacy Policy and Cookie Policy pages.
9. Links to other sites
The site contains links to third-party platforms such as Instagram and YouTube. ONNA HAIR is not responsible for the content or privacy practices of these platforms.
10. Availability of the site
We make every effort to keep the site running without interruption or errors, but interruptions may occur due to maintenance, technical faults or service providers. We cannot be held liable for indirect damage that may result from such interruptions.
11. Changes to the terms
We may update these terms from time to time. The current text is always published on this page and the date above is updated.
12. Applicable law
These terms are governed by the law of the Republic of Türkiye. The Istanbul (Çağlayan) Courts and Enforcement Offices have jurisdiction over disputes. Visitors who are consumers retain the right to apply to the Consumer Arbitration Committee and Consumer Courts at their place of residence under Consumer Protection Law No. 6502.
