Biotech Joins Doctors Inc., Driving Medical DX

Biotech Co., Ltd. (hereinafter 'Biotech') is pleased to announce its participation (group-in) in Doctors Co., Ltd. (Head office: Minato-ku, Tokyo; President and CEO: Takao Yanagawa; hereinafter 'Doctors'), a company leading medical DX.

Background and Purpose: The Evolution of 'Biotech' Realizing 'Next-Generation Hair Growth' by Fusing Hair Science and Medicine

Since its founding in 1981, Biotech has led Japan's hair growth industry for over 40 years. It proudly holds the distinction of being the first in Japan to acquire a patent for a 'hair growth/regrowth system,' and its track record of deeply addressing the hair concerns of over 230,000 individuals is unparalleled in Japan.

Through this group integration, Biotech's long-cultivated assets, including '230,000 cases of performance data and unique hair theory' and 'hospitality-filled customer service,' will be fused with Doctors' 'Doctors Station®' and the advanced medical knowledge of over 700 'Expert Doctors®.' This aims to provide society with a unique 'next-generation comprehensive hair growth Biotech platform' that combines specialized salon care with online counseling, online medical consultations, and AI analysis.

Key Initiatives: Building the 'Biotech Platform' Through a Tripartite Approach

At the core is the medical DX infrastructure provided by Doctors, integrated with Biotech's 'stores' and cutting-edge 'OEM services.' Hair growth is approached as part of holistic health management, realizing a multi-faceted, evidence-based approach.

The construction of this platform will maximize users' 'power to grow hair' through the following three pillars:

1. Provision of the 'Biotech Platform' Connecting Stores and Medical Care

Based on 'Doctors Station®,' this platform will create an environment where Biotech users can access full-fledged 'AGA support services' from affiliated medical institutions, as well as one-stop chat consultations with specialists and concierges.

2. 'Hybrid Hair Growth Care' Based on Medical Evidence

This fuses Biotech's proud salon-based, highly hospitable 'techniques' and 'counseling' with the 'medical approach' supervised by Doctors' Expert Doctors. Furthermore, by developing and introducing precise AI-powered scalp analysis, we aim to provide personalized care optimized for each individual's condition.

3. Expansion of Hair Growth Solutions Through OEM Collaboration

Through the platform, excellent external OEM services (such as state-of-the-art hair growth devices and high-performance supplements) will be flexibly incorporated. This will enable salons to function as a 'comprehensive hub for hair and wellness,' achieving comprehensive hair growth and well-being from both internal and external aspects.
