Quick answer: Xcellerate35 is Thin Lizzy's spray-on hair serum, made with 35 ingredients including castor oil.

If you've been looking at hair serums, you've probably come across Xcellerate35. It's one of Thin Lizzy's best-known products in New Zealand, and it's easy to see why people are curious: it's a simple spray you use at home, with no rinsing and no complicated steps. Here's what it is, what's in it, how to use it properly and what to expect, so you can decide whether it suits your routine.
What Is Xcellerate35?
Xcellerate35 is a leave-in hair serum in a spray bottle. You apply it to clean, damp hair, work it into your scalp with your fingertips and then brush it through. Because it's a light spray, it fits easily between your shower and your hairdryer, and it doesn't need to be washed out.
It's a cosmetic hair care product, designed for people who want their hair to look and feel its best. It isn't a medicine, and it isn't a substitute for advice from your GP. If you notice sudden or significant shedding, patches, or shedding along with other symptoms, see your GP first.
What's in Xcellerate35?
As the name suggests, the formula contains 35 ingredients. One of the key ones is castor oil, a rich oil that has been part of hair care routines for generations. Castor oil is known for helping hair feel conditioned and look glossy. In Xcellerate35 it comes in a light spray, so you can apply it straight to the scalp and roots without the heavy, greasy feel of a pure oil.
Who Is Xcellerate35 For?
- Fine or flat hair: anyone who wants their hair to look fuller and healthier.
- Growing out a style: anyone who wants their lengths to look and feel cared for while they grow out a cut.
- Busy routines: people who want a simple daily step at home rather than a complicated regime.
- Partners, too: it isn't gender-specific, so it can sit on a shared bathroom shelf.

How to Use Xcellerate35
- Wash your hair: use your usual shampoo and conditioner, then towel-dry so your hair is damp, not dripping.
- Section your hair: part it in a few places so you can reach your scalp.
- Spray onto the scalp: spray along each part. The product page suggests 5 to 10 pumps a day.
- Massage it in: use your fingertips to work the serum into your scalp for about a minute. Keep the pressure light.
- Brush through: gently brush from root to tip so the product is spread evenly through your hair.
- Style as usual: dry and style your hair as normal, keeping heat on a lower setting where you can.
- Repeat daily: consistency matters more than quantity, so make it part of your everyday routine.
How Long Should I Use It Before I Judge It?
Hair care is a slow game, so give any new routine a fair run. Use Xcellerate35 every day as directed, and take a photo in the same light at the start so you have something to compare against later, rather than relying on memory. Everyone's hair is different, so your experience will be your own.
Tips to Get More From Your Hair Routine
- Brush gently: start at the ends and work up, rather than dragging a brush through knots from the top.
- Go easy on heat: lower your styling temperature and use a heat protectant to help keep breakage from styling down.
- Loosen up: very tight ponytails and buns pull on hair, so give it a break with softer styles.
- Eat well: a balanced diet with enough protein is good for your overall wellbeing.
