The combination of GHK-Cu and Keratin targets the most common hair concerns at the source:
• Structural Repair — GHK-Cu supports collagen and elastin production in the scalp, helping strengthen hair anchoring
• Keratin Restoration — Hydrolyzed Keratin penetrates the hair cuticle and helps repair damaged areas from within
• Moisture Balance — Argan Oil and Jojoba Oil lock in moisture without leaving heavy residue
• Less Hair Breakage — Copper peptides help strengthen keratin bonds, reducing split ends and breakage
• Scalp Support — The anti-inflammatory properties of GHK-Cu help calm irritation and itching
GHK-Cu helps regulate genes involved in the extracellular matrix — the structural network that supports and anchors hair follicles.
• Pickart (2008): GHK-Cu was shown to regulate genes linked to collagen, elastin, and glycosaminoglycans — all essential for healthy hair follicles
• Abdulghani et al. (1998): Topical copper peptides improved hair density and follicle diameter in a 6-month study
• Keratin Research: Hydrolyzed Keratin penetrates the hair cuticle and helps repair the protein structure from within — something silicones cannot do

Over 4,000 studies. 1% copper peptides + Hydrolyzed Keratin. Repairs hair structure — instead of coating it.
GHK-Cu + Keratin + Argan oil + Panthenol. No fillers. Every ingredient has a function.
No silicones. No artificial coating. Real structural repair. Week four — you see the difference.
Most conditioners coat your hair with silicones. CU Conditioner repairs it — with copper peptides and bioidentical fatty acids.
GHK-Cu stimulates collagen and elastin production in the scalp and strengthens hair anchoring from the root.
Hydrolyzed Keratin penetrates the hair cuticle and repairs damaged areas from the inside — real repair, not coating.
Locks in moisture without clogging pores or leaving heavy residue. Lightweight and effective.
Copper peptides strengthen the disulfide bonds in keratin. This measurably reduces split ends and breakage.
The anti-inflammatory properties of GHK-Cu relieve itching and irritation — especially for sensitive scalps.
Not silicone shine, but natural shine from a repaired hair cuticle and strengthened lipid layer.
Silicones coat your hair. Copper peptides and keratin repair it from within.
1% GHK-Cu — the highest copper peptide concentration on the market for a conditioner. 10x more than the average.
Hydrolyzed Keratin penetrates the hair cuticle and repairs the protein structure — not coating, but rebuilding.
No hidden dosages. No silicones. Everything on the label.
Copper peptides — repair hair structure and strengthen follicles
Stimulates scalp circulation and extends the anagen phase
Repairs damaged hair from within, reduces split ends

GHK-Cu — while the average is 0.01–0.1%
Copper peptides strengthen hair structure from the outside. Keratin repairs it from within. Together: real regeneration.
Pickart (2008): GHK-Cu regulates the expression of genes responsible for the extracellular matrix — the scaffold in which hair follicles are anchored.
Abdulghani et al. (1998): Topical copper peptides improved hair density and follicle diameter in a 6-month study.
Keratin research: Hydrolyzed Keratin penetrates the hair cuticle and repairs the protein structure from within — something silicones can never do.
"Most conditioners coat hair with silicone — it looks smooth but the damage underneath continues. GHK-Cu combined with hydrolyzed keratin takes a fundamentally different approach: the peptide strengthens the dermal matrix where follicles are anchored, while keratin rebuilds the actual protein structure of the hair shaft. That's repair, not masking."
Apply after washing. 2–3x per week for optimal results.
Apply to damp hair after washing
Focus on lengths and ends, gently massage into the scalp
Leave on for 3–5 minutes (or 10–15 min. as a hair mask)
Rinse thoroughly with warm water
"First conditioner that actually detangles without leaving silicone residue. My curls are defined and bouncy again. Combined with CU Shampoo it's the best combo I've ever used."
"Color-treated hair that was breaking off at the ends. 6 weeks of CU Conditioner and the breakage has stopped. My colorist noticed the difference before I even mentioned the product."
"I use it as a 15-minute hair mask once a week. The keratin repair is real — my split ends are visibly reduced and the hair feels stronger, not just coated. Huge difference from silicone conditioners."
"Good conditioner, hair feels soft and manageable. The copper peptide angle is interesting but I'm only 4 weeks in. Giving it more time for the full keratin rebuilding effect."
"My hair was destroyed from years of heat styling. Tried protein treatments, olaplex, everything. CU Conditioner is the first thing that's making my hair actually feel stronger, not just temporarily smooth."
"As a man with long hair I never found a conditioner that didn't weigh it down. This one is lightweight, no buildup, and my hair is noticeably thicker at the roots after 8 weeks."
"Postpartum hair was falling out in clumps. Started the shampoo + conditioner duo at month 3. By month 5, the shedding stopped and I have baby hairs growing everywhere. Cannot recommend enough."
"The ingredient list convinced me — hydrolyzed keratin + copper peptides instead of dimethicone and silicones. After 10 weeks my hair has natural shine again, not that fake silicone gloss."
CU Conditioner — 1% GHK-Cu copper peptides with Hydrolyzed Keratin. Silicone-free. For all hair types. With a 30-day money-back guarantee.
