Why it works

The clog in the shower drain that made you cry a little — this is for that.

01

Months after the baby, your hair is falling out in handfuls and your part looks wider.

Botanical Density Serum

A clean botanical serum you massage in daily supports the look of fuller hair and helps you feel like you're finally doing something about the shed.

02

You want something natural, not a chemical you're unsure about while you're still nursing.

Botanical Density Serum

This is a plant-powered, fragrance-free serum built on rosemary, ginger and spirulina — a gentle daily step for the post-baby season.

03

Hair treatments usually leave your hair greasy and flat.

It's a lightweight leave-in that absorbs into the scalp, so your hair stays clean-looking, not weighed down.

  • Rosemary leaf extractThe same herb from the kitchen garden, drawn out into a scalp extract.Rosemary is the best-known scalp botanical there is, and it is the one people go looking for by name. It supports a healthy-looking scalp — the environment your hair grows out of — for fuller-looking hair.
  • Ginger root extractA warming root extract, the same plant you grate into food.Ginger brings a gentle warmth to the scalp that pairs with the daily massage. Together they support the look of vitality where hair has gone flat and tired.
  • Spirulina and chlorella algae extractsTwo green freshwater algae, packed with plant protein, minerals and pigment.They are the conditioning heart of the serum. These extracts feed the scalp plant nutrients so strands feel stronger and look less fragile at the root.
  • Baicalin and Scutellaria baicalensis root extractA root from the mint family, long used in traditional practice, and baicalin, the antioxidant it is rich in.It helps keep the scalp looking calm and comfortable rather than irritated. A settled scalp is the quiet part of the routine that makes everything else easier to keep up.
  • Licorice root extractA sweet root extract used in skincare for generations.It is a soothing botanical that supports an even, comfortable-looking scalp — helpful when daily massage is part of the plan.
  • Vitamin C (ascorbic acid) and vitamin E (tocopherol)Two familiar antioxidant vitamins.They protect the botanicals in the bottle from going off, and they add everyday antioxidant care at the scalp. Two jobs from one pair of ingredients.
  • Water, glycerin and propanediolThe base the serum is built on — water with two gentle moisture-holding liquids.This is why it feels light instead of greasy. It carries the botanicals right to the scalp, absorbs quickly, and leaves nothing coating your hair.
  • Wheat germ and soybean germ extractsTwo nourishing seed extracts rich in natural vitamin E.They condition the scalp alongside the algae. Please note them if you have a wheat or soy allergy — we would rather flag it plainly than bury it.
  • Sodium benzoate and potassium sorbateA gentle, widely used preservative pair, also found in everyday foods.A water-based botanical serum has to be protected or it spoils. This mild pair keeps every bottle fresh and safe for the full 90-day routine without harsh preservatives.

Questions, answered

What does this actually do for thinning hair?
It supports the look of fuller hair, less visible shedding and strands that feel stronger — massaged into the scalp once a day. Here is the honest version: our Botanical Density Serum is a cosmetic scalp serum built on rosemary, ginger, licorice and Scutellaria root with spirulina and chlorella, and it works on the appearance of your hair and the look of a healthy scalp. What it asks of you is simple: daily use and a full 90 days.
Is this a hair-loss treatment?
No — it's a cosmetic scalp serum, not a drug, and it doesn't treat any medical cause of hair loss. If something medical is going on, a doctor is the right person to see, and this serum can sit alongside whatever they advise. What it does do is support the look of fullness and a healthy-looking scalp, day after day.
Can men use it too?
Yes. There is nothing in this serum that only suits one person — rosemary, ginger and spirulina support the look of a healthy scalp on anyone. Apply it along the part or wherever thinning shows, massage it in, and give it the same 90 days.
Is it okay on coloured or heat-styled hair?
Yes. The Botanical Density Serum goes onto the scalp rather than down the lengths, so it will not strip or shift your colour. If your hair takes a lot of heat, this daily routine is exactly the kind of steady care that helps strands feel stronger.
How much do I use, and do I rinse it out?
A small dropper's worth once a day, and no — it's a leave-in. Part the hair and apply along your part and any thinning areas on a dry or towel-dried scalp, then massage it in with your fingertips. Towel-dried or dry is ideal so it lands on the scalp rather than running off wet strands. Style as normal afterwards.
Will it make my hair greasy, or mark my pillow?
Neither. It's a lightweight, water-based leave-in that absorbs into the scalp rather than coating the hair or sitting on top like an oil, so hair stays clean-looking through the day and your pillowcase stays clean too.
Does it have a scent?
It is fragrance-free. You will catch a faint green herbal note from the botanicals themselves, and that fades within minutes.
Can I layer it with a scalp oil?
Yes, and it's a lovely pairing. Many people use this serum daily and add Austin Bloome Hair Oil for Scalp Health and Hair Growth as a weekly massage. The rule of thumb is simple: lightweight serums go on first and get a moment to absorb, then any oil goes over the top.
How long until I see a difference?
Give it a full 90 days of daily use. Hair grows on a slow cycle, so the look of fullness and less visible shedding builds gradually rather than arriving overnight — that's the honest timeline, not a soft one. It's also why our guarantee runs 100 days: massage it in daily, and if your hair doesn't look fuller at the end of it, you're covered.
How long does one bottle last?
Around two months with daily use. Because hair needs a full 90-day cycle to show anything, a multi-bottle bundle is the practical way to cover the whole run without a gap, and Subscribe & Save keeps the next one arriving on time so you never stop halfway. You can cancel whenever you like.
How should I store it?
A cool, dark shelf with the cap on, away from heat and direct sunlight, keeps the botanicals fresh.
What is in it, and what is left out?
In: rosemary, ginger, licorice and Scutellaria root botanicals, spirulina and chlorella algae, plus vitamins C and E, in a light water-and-glycerin base. Left out: fragrance, and any drug active. Worth knowing if you have allergies — it does contain wheat germ and soybean germ extracts.
Can I use it while pregnant or breastfeeding?
It's a fragrance-free botanical serum you massage into the scalp rather than something you swallow, and it's most often reached for during the postpartum shed. Everyone's situation is different, so please run it past your provider before starting anything new while you're pregnant or nursing. If you're looking for more support through this season, our Pregnancy and Postpartum collections are built for exactly where you are.
How is it different from the peptide hair serum?
This is the gentler, plant-powered daily option — botanicals, algae and vitamins, lovely for the postpartum season or for thinning that's early on. Austin Bloome Peptide Hair Growth Serum is the higher-strength, targeted step with peptides for thinning that has progressed further. Plenty of people start here and add that one later.
Is it worth it — and what if it isn't for me?
A bottle is roughly two months of a daily, fragrance-free botanical scalp routine that supports the look of fuller hair. Give it the 90 days it honestly needs, and if your hair doesn't look fuller, our 100-Day Money-Back Guarantee gives you your money back, bottle included — the only thing you lose is the postage.
