How do I use it?
Apply to wet hair. Gently massage your scalp for 2–3 minutes, then rinse thoroughly. Use 2–3 times a week. Avoid contact with eyes. Follow the directions on your tube.
What is inside?
Caffeine, niacinamide (vitamin B3), panthenol (provitamin B5), zinc PCA and glycerin are part of the Densea formula. See the ingredient highlights below and the complete ingredient list on your tube.
It is not just how much hair you have. It is how each strand looks.
Finer strands give your scalp less coverage. That is why a brighter bathroom light, wet hair or a photo from above can make a change feel suddenly noticeable. Scalp buildup and hair that feels dry can make your everyday routine harder, too.
Densea focuses on the part of that routine you can change today: how you cleanse and care for your scalp and hair.
A simplified illustration of miniaturization.

at the roots.
Your scalp deserves the same care as your lengths. Massage the DensiFuse gel directly onto your scalp to distribute caffeine, B3, B5 and zinc PCA from the roots through your strands. Cleansing and care, brought together in the wash you already take.

DENSEAGood questions. Clear answers.
Is Densea for women or men?
Both. Densea was developed for women and men. The formula is the same, whether you keep your set for yourself or share it.
Is this a shampoo or a leave-in serum?
It is a rinse-off care shampoo. Apply to wet hair, massage gently for 2–3 minutes and rinse thoroughly. It replaces your usual shampoo; there is no extra leave-in step.
How often should I use it?
Use 2–3 times a week, following the directions on your tube. Gently massage your scalp and rinse thoroughly. Avoid contact with eyes.
How long does one tube last?
Each tube contains 8.45 fl oz / 250 mL. How long it lasts depends on hair length, the amount you use and how often you wash. With the Daily Duo, your next tube is ready when you need it.
Which set should I choose?
We recommend the Daily Duo: two tubes for $49, or $24.50 each. That is $19 less than buying two Single tubes. The Complete Set gives you our lowest price per tube: four for $84, or $21 each. Every option is a one-time purchase.
Will I be signed up for a subscription?
No. There are no recurring charges, automatic refills or subscriptions on these sets. You decide when to order again.
Do you ship to the US?
Yes. Standard US shipping is free. Available delivery options and the current estimate are shown at checkout. Your shipping confirmation includes tracking. Questions? Email support@colagea.com.
Does Densea replace a hair-loss treatment?
Densea is a cosmetic care shampoo, not a medicine or a substitute for prescribed treatment. If you have sudden or persistent hair loss, speak with a dermatologist about the cause and the care that is right for you.
How does the 90-day results guarantee work?
Use Densea as directed for 90 days and take comparable photos on days 1, 30, 60 and 90. If you see no visible improvement, email your order number and those four photos to support@colagea.com within the following 30 days. Eligible claims receive a refund of the price paid for the relevant product, including launch sets. See our Guarantee & Returns page for the full terms.
