What Results Could Look Like in Less Than 3 Months
"I was hesitant after trying countless products, but 3 months of TSR changed everything. My shower drain isn't clogged anymore, my scalp feels healthier, and I have baby hairs sprouting all around. My stylist noticed the change as well." - Emily J.
"After losing 50% of my hair due to hormonal issues, I dreaded wash days and avoided them as long as possible. Now with these capsules, I barely see any shedding when I run my fingers through my hair! I've stopped using fibers to hide my scalp and my previously thick hair is coming back." - Sofia W.
"A lot of my hair grew back in just 3 weeks. I'm super impressed." - Claire D.
Turn. Squeeze. Brush.
Sixty seconds, once a day. No rinsing, no second product, nothing to overhaul. Wet or dry hair, morning or night, whatever fits.
Turn.
One turn unlocks it and primes the tube for dispensing. It stays primed, so this is a first-use step more than a daily one.
Squeeze.
Press it on the skin where you're thinning — part line, temples, crown
Brush.
Massage with the built-in brush to spread it and boost circulation. No rinsing. Style straight over the top.

Ninety days, honestly.
Hair grows on its own schedule, and no serum changes that. Here's what actually happens, and when.
Weeks 1-2
The scalp settles
Cleaner, less itchy scalp. The cooling hits the moment it lands. Caffeine starts waking tired follicles. Nothing visible yet, and nothing should be.
Weeks 3-5
Less shedding
Far less hair circling the drain, fewer strands on the brush. Roots feel more anchored. This is the first real signal, and most people hit it by week 4.
Weeks 6–8
Baby hairs at the line
Tiny baby hairs along the hairline. The part starts reading narrower. Hair feels thicker with more body, and other people notice before you do.
Week 8+
Fuller, healthier-looking hair
Thinning areas fill in and the ponytail feels heavier. This is where you judge density — not before.
You were treating the wrong layer
Biotin. Rosemary oil. Thickening shampoos. Maybe minoxidil. If you're reading this past 45, you've probably tried at least two.

Oils sit on top
Heavy on the lengths, nowhere near the root, and they ruin the style you spent time on.
Supplements go everywhere
Swallowed, diluted, spread across your whole body. Your scalp gets whatever's left, at $79 a bottle.
Minoxidil is hard to live with
It does reach the scalp — but it's daily for life, with irritation, texture changes and the shed if you stop.
This goes where hair is made
The brush parts the hair and lays a water-light formula directly on the scalp. Sixty seconds, once a day.
Six scalps. Six timelines.
One serum.
Every pair is the same woman, same phone, same bathroom light, weeks apart — all between 45 and 58.
Part line, week 1 to week 12
Post-menopause grey, week 1 to week 12
Hairline, week 1 to week 7
Front section, week 1 to week 17
Blonde and fine, week 1 to week 12
Six actives you'd recognize from your skincare shelf
Nothing exotic, nothing hormonal — ingredients you already trust on your face, sent to the skin they've never reached.
Wakes the follicle
CaffeineBiotin
Caffeine supports circulation at the root, where the growth cycle is decided. Biotin helps maintain strong, healthy-looking strands.
Balances the scalp
NiacinamideHeartleaf Extract
Niacinamide supports the scalp barrier, while heartleaf — a Korean botanical — calms the dry, reactive scalp that makes hair look thin at the root.
Hydrates and strengthens
PanthenolGlycerin
Glycerin binds moisture to the scalp, while panthenol conditions the hair for softness, strength and the look of thickness.
Protects the follicle environment
Green Tea Extract
Camellia sinensis leaf extract is rich in antioxidants that help protect the scalp and support a healthy follicle environment.
Fragrance-free
Water-based formula
Every hair type, 1A–4C

What we're not going to tell you
That you'll see results in fourteen days. You won't — and neither will anyone else, no matter what the ad said.
What we can tell you is what happens and when. We'll check in at day 14, day 30 and day 60, so you know whether this is working while your guarantee is still open.
If it isn't working by day sixty, email us and we refund you. That's the whole deal.
What customers say
The applicator is why I actually use it
After several weeks of consistent use my hair feels stronger, falls out less when I brush it and looks healthier. The built-in brush makes it very easy to get the product onto the scalp without wasting any.
Half of what used to come out in the brush
tried every hair vitamin. biotin in every dose. collagen powders. not one of them did anything measurable. this goes directly to the scalp which is where the problem actually is. seems obvious when you think about it. 6 weeks in and the difference is already visible
Five weeks before I was sure, but the drain does not lie
Postpartum hair loss is no joke. Lost so much after my second baby I was genuinely scared. Doctor said wait it out but 7 months later it wasnt getting better. Started this and by week 5 the shedding slowed down a lot. Now at week 10 i have little baby hairs at my temples!! so happy
Outstanding Quality
I've been shopping with this brand for over a year now and the quality never disappoints. Every purchase has exceeded my expectations and their customer service is exceptional.
Noticed a huge decrease in shedding after the first bottle
Already ordered more so I do not run out.
Sceptical of TikTok products, the ingredients checked out
I am usually super doubtful when it comes to TikTok hair products, but the heartleaf and caffeine combo seems to be working for me. Hair feels denser and I am not seeing nearly as much shedding in the shower.
My ponytail stopped getting thinner
The shedding slowed down first and the ponytail stopped shrinking after that. Month to month it is subtle, but scrolling back through my photos the difference is obvious.
Shower drain is clear, growth is slower
Eight weeks of using it every night. The shedding was the first thing to change and it changed a lot. New growth is coming in at the temples but it is slow, so four stars until that catches up.
Frequently Asked Questions
I've tried everything and nothing worked. Why would this be different?
+
Most of what you've tried works on the strand — the part of your hair that's already dead. Biotin is swallowed and diluted. Rosemary oil sits on the lengths. Shampoo has ninety seconds of contact before it rinses away.
This is applied to the scalp with a brush, and stays there. It's not a better version of what you tried. It's a different layer.
If I stop using it, will my hair fall out?
+
No. This is scalp care, not a medication — there's no rebound cycle when you stop.
Consistency gives you the best result, the same way it does with skincare. But stopping doesn't undo what you've built.
How long does it really take?
+
Less shedding in one to three weeks. Baby hairs at four to eight. Visible density at two to three months.
If anyone tells you fourteen days, they're selling. That's why the plan is ninety days and the guarantee is sixty.
Will it make my hair greasy?
+
No. It's a water-light formula, not an oil. It absorbs in seconds and leaves no residue, so you can apply it in the morning and go straight out.
Does it work with my hair type?
+
Yes — 1A through 4C. It's applied to the scalp, not the hair shaft, so curl pattern and porosity don't change how it works.
Fragrance-free, so it's suitable for sensitive scalps, tight styles and thinning edges.
Can I use it with minoxidil or HRT?
+
Yes. TSR is non-hormonal and minoxidil-free, so it fits alongside anything your doctor prescribed — HRT, minoxidil, spironolactone or supplements. Apply it at a different time of day than any other scalp treatment: TSR in the morning, your treatment at night. It doesn't replace what you're already using, and it won't interfere with it.
My hair started falling out after fast weight loss this year. Will this help?
+
Shedding after rapid weight loss is one of the most common reasons women 45+ find us. It's a follicle-cycle problem — exactly what TSR works on. Most notice less shedding within the first month.
Can I use it on color-treated hair?
+
Yes. It's applied to the scalp, not the lengths, so it won't affect color, keratin treatments or chemical processing.
