How do I use it?
Part your hair: Expose the areas of your scalp where you want to apply HZA.
Spray directly: Apply the fine mist directly onto the scalp, focusing on thinning areas, sparse edges, and your part line.
Massage gently: Use your fingertips to work the formula into the scalp for a few seconds.
Leave it in: No rinsing is needed. Let HZA absorb and continue with your normal routine.
Is this right for me?
HZA is made for women looking to give extra care to areas where their hair appears thinner or less dense.
- Widening part lines
- Thinning crown and temples
- Sparse or thinning edges
- Excessive-looking shedding
- Dry or neglected scalp
How soon will I see a difference?
Consistency matters most. Some customers first notice less shedding and a healthier-feeling scalp, while visible changes in the appearance of hair density can take longer.
For the best chance of seeing a difference, make HZA part of your regular routine and give your hair time to respond.
Individual results may vary.
Is it suitable for all hair types?
HZA's lightweight, water-based formula is designed to fit easily into a wide range of hair-care routines, including straight, wavy, curly, and coily hair.
Because it is applied directly to the scalp, you can target the areas you care about without coating the rest of your hair in heavy oil.
How does HZA work?
HZA delivers a lightweight blend of rosemary extract, rice water, glycerin, and supporting botanicals directly to the scalp.
The fine mist lets you focus the formula along your part, crown, temples, and edges without the heavy, greasy buildup of traditional scalp oils.
How often should I use it?
HZA is designed to be easy to work into a consistent hair-care routine. Apply it according to the directions on your product label, focusing on the areas that need the most attention.
Consistent use is more important than over-applying the formula.

Before-and-after comparison for people with severe hair loss.
My hair was looking noticeably thinner around my temples. After using HZA consistently, it feels healthier and looks fuller. I’m so much more confident with my hair now.

Real Hair. Real
Results.
Less hair in the drain. Fuller-looking edges. A part that looks less sparse. Here's what HZA customers are sharing. In their own words.
Tested by users experiencing severe hair loss
"Finally seeing fuller-looking hair."
The biggest difference for me has been consistency. After using HZA every day, I started noticing fewer loose hairs and my hairline looks healthier than it has in years.
"My hair feels so much fuller."
I wanted something easy to use on my thinner areas. HZA sprays right where I need it, absorbs quickly and never leaves my roots feeling oily or weighed down.
"I notice far less shedding now."
I used to notice loose strands constantly when brushing and washing my hair. Since making HZA part of my routine, my hair feels stronger and much easier to manage.
"My part doesn't look as wide."
My widening part was what bothered me most in photos. After staying consistent with HZA, my hair looks much more filled in when I style it.
"My edges finally look healthier."
My edges were always the area I noticed first. HZA takes seconds to apply where I need it and fits perfectly into my morning routine.
"Finally something that isn't greasy."
I tried heavy rosemary oils before and hated the buildup. HZA gives me the scalp routine I wanted without making my roots look greasy.

Why Hair Products Keep Failing You
(It's Not Your Fault)
Tested by users experiencing severe hair loss
Your scalp is built to keep things out — sebum, dead skin, and a layer of hair in the way.
So when you drip on a heavy oil or serum, most of it never reaches your scalp: it coats the hair, looks greasy for an hour, and washes away that night.
And most hair products don't even give you real ingredients you can trust — just a watered-down formula behind a pretty label.
HZA® addresses both with rosemary and fermented rice water in a weightless, water-based mist that sprays directly onto the part line and scalp without the heavy, greasy buildup of traditional oils.

“12 week update because I promised myself I'd track this honestly. First few days = surprisingly noticeable thickness, my hair just felt different in hand. Around the 3-4 week mark is when I started seeing actual new growth at my scalp. It wasn't dramatic overnight, more like a slow steady thing week by week. By 12 weeks the change from my before photos is honestly kind of embarrassing how big it is lol. Non-greasy formula is also a huge plus, I use it every morning and it just absorbs.”

“I've tried SO many hair growth products that did nothing so I went in with zero expectations. The non-greasy part sold me first since most oils leave my hair looking dirty by noon. But then within the first week I noticed my hair had more body, and by week 6-7 I was seeing actual new growth around my temples where I've always had thinning. 12 weeks later and it's not even comparable to where I started.”

“9 weeks in and this photo is literally from my bathroom mirror, no filter, nothing staged. My hair was already pretty long so I wasn't expecting a crazy difference, but you can actually see it's thicker now — more volume through the ends, way less of that flat/stringy look I used to get by the end of the day. First week or so I just noticed it felt fuller in my hand, then around week 4 I started seeing shorter regrowth strands near my part. At 9 weeks the overall fullness is the biggest change for me, still non-greasy even with how much I'm using daily. Genuinely didn't think a spray could do this much.”
