Why dry ends while growing out hair led to Cheongdam salon Beorn Hair
I've been growing out my hair pretty seriously lately, but the longer it gets, the drier and more damaged the ends become, and it's been bothering me a lot. When you're trying to grow your hair out nicely, length matters, but the health and texture of the hair itself matters even more. No matter how much rinse or hair mask I did at home, it only softened the surface for a moment — the dryness and tangling inside never really got fixed. So I decided I needed proper professional care and headed to Beorn Hair Cheongdam, well known as a Cheongdam-dong hair salon.

Hair consultation with Deputy Director Ko Do-hee
This time I specifically requested Deputy Director Ko Do-hee. As soon as I arrived, she carefully checked the condition of my hair and gave me a detailed consultation on exactly what nutrients my hair needed right now. She pinpointed my hair's condition and kindly explained the direction of care needed, which gave me a lot of confidence before we'd even started.

What is the Inner Treatment Clinic at Beorn Hair Cheongdam?
The treatment I received this time was Beorn Hair's own signature program, the Inner Treatment Clinic. Apparently it uses a patented cohesive-bonding technology that firmly refills the keratin protein structure that determines the internal framework of the hair. It clearly runs on a well-organized, systematic process, and receiving it in person, it exceeded my expectations.
The step-by-step process was also very intuitive and thorough. Let me walk through the 7 steps I experienced in order.


Steps 1–2: Detox shampoo and protein refill
1. Detox shampoo: The very first step cleared out buildup and residue on the surface of the hair. It's a prep stage that clears the base so the highly concentrated care products applied later can absorb deep into the hair.
2. Protein replenishment: Once the base was cleared, the real work of refilling keratin protein began. High-content protein fills in the hollowed-out, damaged parts of the hair, raising density and making it firmer and softer.


Steps 3–4: Heating cap and moisture refill
3. Heating cap: Rather than just applying protein on the surface, a heating cap is used to reliably drive it deep into the hair. This heat process helps the active ingredients penetrate effectively.
4. Moisture replenishment: After the protein work, a moisture step follows that fills the dried-out interior of the hair with NMF (natural moisturizing factor). This balances the hair's oil-water levels and builds a moist, flexible base.


Steps 5–6: Nano steam and CMC refill
5. Nano steam: While moisture is being supplied, a nano steam device is also used. The fine steam particles gently open the hair's cuticles, maximizing how quickly nutrients absorb and dramatically improving how well the clinic's nutrients last. It felt warm and wonderfully hydrating.
6. CMC replenishment: Next comes the CMC replenishment step, which drives protein, moisture, and lipid components very deep into the hair to firmly strengthen bonding with the cuticle. It acts as the link connecting the hair's structure and moisture, playing a key role in how long the results last.

Step 7: Strengthening the protective coating
7. Protective coating reinforcement: Finally, so all the nutrients that were just packed in don't easily escape, this step repairs the cracked, peeling cuticle on the hair's surface and forms a strong protective coating. Once finished, I could actually feel the shine and firmness running through my whole head of hair with my fingertips.



How the hair looked and felt after the 7-step clinic
Throughout the whole process, Deputy Director Ko Do-hee and the staff handled my hair with real care and explained each step kindly, so I could relax through the whole treatment.
After the whole clinic was done and I dried my hair and ran my hands through it, I really could feel a clear difference. The tangling that used to catch on my fingertips vanished as if it had never existed, and I got a sense of weight and solid bounce that felt like it came from deep inside the hair. It didn't feel like a superficial silicone-coated shine — my hair itself felt firmer and more hydrated, which was really satisfying.


Going through this made me realize once again that when you're growing your hair out nicely, clinic care to protect the hair's own health matters even more than styling. If you're growing your hair out without cutting it, like me, or struggling with damaged hair, I really recommend getting the Inner Treatment Clinic with Deputy Director Ko Do-hee at Beorn Hair Cheongdam, the Cheongdam-dong hair salon!
