Fewer strands in the shower. Fuller hair in the mirror. It starts with marine collagen.

holi (mane) pairs wild-caught collagen with saltwater pearl powder, and it disappears into your morning coffee. Customers notice less breakage in the brush first, then hair that feels thicker.

It was never your fault. You were sold the wrong fix.

Most of us have a drawer of things that were supposed to help.

  • Biotin gummies
  • Hair vitamins
  • Expensive shampoos
  • Cheap collagen

Here's what they miss. Your hair is made of protein, and your body needs a steady supply to keep building it. A typical hair gummy gives you biotin, some sugar and almost no protein at all. Biotin only makes a difference if you're low in it, and most people aren't.

holi (mane) gives your hair the real thing. Wild-caught marine collagen (up to 24g of protein in two to three scoops), plus saltwater pearl powder for calcium, silica and 30+ trace minerals. Two ingredients your hair actually uses, in the coffee you're already drinking.

Two lattes made with holi (mane), next to the bagFrom Jaimee S.'s review

"Fish collagen? In my coffee?"

Fair question. Marine collagen has a reputation, and plenty of powders earn it with a fishy smell or a bovine aftertaste. That's usually the moment people start skipping days, and skipped days are why hair supplements "don't work."

holi (mane) is odorless and close to tasteless. Stir it into your latte, matcha or smoothie and you won't know it's there. It's the most mentioned thing in our reviews.

"It dissolves well, doesn't have a weird flavor and seems to be doing its job."Rebekah S., holi (mane) review
"It has a slight smell to it, but it is not a problem when mixed with coffee."Laura I., holi (mane) review

"I switched to a cheaper collagen. My hair paid for it."

Two stories we hear a lot

"In order to cut costs for a few months I decided to stop buying it and switch to a cheaper collagen. My nails, skin, and hair suffered for it."

"My nails became brittle and would constantly break, my hair not only shed more, but the overall strength of my hair began to deteriorate. I started buying it again… it wasn't even a month of taking it daily that I noticed my hair, skin, and nails begin to improve again."

Murr J.holi (mane) review

"It is not a quick cure but it is reliable and steady if you are patient."

"I had severe damage to my hair after having extensions for two years and it has been a long road to recovery. I use one scoop of holi mane in my coffee every morning for the past 6 months and my hair is visibly thicker and healthier."

What's inside holi (mane)

Two supplements in one, with nothing you have to choke down

24g

Up to 24 grams of protein

In two to three scoops. The building block your hair is made from, which most hair gummies leave out.

I–IV

Four types of collagen

Types I, II, III and IV, listed right on the label. Most marine collagen is almost all type I.

30+

Trace minerals from saltwater pearl

Calcium, silica and magnesium among them, for the parts of your routine collagen alone doesn't cover.

Wild

Wild-caught North Atlantic fish

Cod, pollock and haddock. Non-GMO and kosher. Not cattle hide.

What customers notice, and when

Hair takes time. This is the pattern we see in reviews.

The first few weeks

Nails usually come first. Less peeling, less splitting, nails you can finally shape and file.

"Within a week started to notice my nails growing and my hair is healthier and stronger, too… less shedding!" Katie O.
Around month two

Less breakage in the brush. Hair that feels softer and shinier.

"This is my 2nd month… I have noticed a change in my hair and nails. Also, there seems to be less breakage." Mallory T.
Month three and on

Hair that looks and feels fuller, with less of it left behind in the shower.

"You truly need to give this 3 months… the decrease in hair shedding I have been experiencing is nothing short of amazing." Robyn L.

Everyone's hair is different and results vary. These are individual customer experiences, not a promise.

She made it for her own hair first

"My hair used to be broken and damaged after coloring, but it is now the longest, strongest, and silkiest it has ever been."

Jena tried and investigated a long list of collagen powders before making her own. Her verdict, in her words: "all collagen is not created equal." So she paired wild-caught marine collagen with saltwater pearl, and holi (mane) became one of Agent Nateur's best sellers.

Nails usually come first, then less breakage, then hair that looks and feels fuller. One bag is 30 days of daily scoops for $99.

How much do I take?

Two to three scoops a day, which gives you 16 to 24 grams of protein.

Can I take it with my multivitamin or biotin?

holi (mane) is a food-based collagen and pearl powder, and many customers take it alongside other supplements. If you take medication or have a health condition, check with your doctor first.

Can I take it while pregnant or breastfeeding?
