Anyone concerned with hair shedding, thinning, buildup, dryness, or scalp imbalance. The formula have been tested on:

Use rhute’s Density + Repair serum daily on dry or damp hair. Follow the below steps:

Step 1: Use our 4 by 4 method. First, divide hair into 4 equal parts

Step 2: Use 1 pipette full per section, dispensing drops evenly along the scalp. One pipette should cover your whole scalp - add a little more if focusing on specific areas like your parting or hairline.

Step 3: Use your fingertips to gently massage the serum into your scalp in circular motions for 1–2 minutes (or up to 5 minutes for extra stimulation).

Step 4: Do not rinse. Leave the serum on your scalp for at least 4 hours to allow full absorption.

Yes! rhute’s Density + Repair Serum was designed to tackle a number of concerns while still being lightweight and easy to layer with the rest of your haircare routine. It won’t interfere with your regular styling products, and with its 16 active ingredients that support your hair health and growth throughout the hair cycle, rhute cuts the fuss — one formula, no time-consuming routine needed.

You can use the serum in conjunction with minoxidil or other hair serums if you choose to. It is best to use these at different times or when one has dried before applying the other.

You may notice immediate relief in scalp comfort and hydration — that’s your first sign it’s working. For density and shedding, consistency is key. After:

• 1 - 2 weeks: Scalp feels soothed. Less dry, itchy and flaky. 
• 4 - 8 weeks: Hair follicles are stimulated and strengthened. 
• 8 - 10 weeks: Follicles are fortified.
• 12 - 16 weeks: Tighter parting, baby hairs that have grown out - and a thicker, fuller ponytail. 

The longer you use the serum, the better the results. Healthy hair takes time. Consistency is key.

No, we went through countless rounds of revisions to get the texture just right. A lightweight, fast-absorbing  formula comfortable enough for daily use. The formula was carefully balanced with ingredients like salicylic acid and niacinamide, which help regulate excess oil and reduce greasiness. That means you can apply it morning or night without worrying about buildup or disrupting your style.

Yes, the formula is safe for colour-treated and chemically processed hair. It’s designed to support scalp and hair health without stripping, drying, or interfering with treatments, making it suitable for all hair types and textures.

With daily use, one bottle lasts about 4 - 6 weeks. If you’re focusing only on specific areas (like a parting or hairline), your bottle may last even longer.

All of the ingredients in our formula are considered safe for use during pregnancy and breastfeeding. However, we always recommend consulting your own medical practitioner before introducing any new product into your routine.

The percentage of salicylic acid in our formula is below 2%, which is within the level considered safe for pregnancy and breastfeeding, as reviewed and confirmed by our regulatory team.

Yes, the Density & Repair scalp serum is vegan and was not tested on any animals.

Yes. rhute’s scalp serum does not contain tree nut or peanut-derived ingredients and is free from common nut allergens such as almond, walnut, hazelnut, macadamia, cashew, pecan, pistachio, Brazil nut, and peanut oils or extracts.

rhute’s scalp serum is fragrance-free and does not contain added perfumes or essential oils. You may notice a subtle, natural scent from the active ingredients - including botanicals and peptides - which quickly dissipates after application. This ensures the formula remains gentle, suitable for sensitive skin, and focused on performance rather than masking its natural profile.

For optimal results, apply rhute’s scalp serum once daily to a dry or wet scalp. Part hair into sections and use the dropper to apply directly to the scalp, focusing on areas of concern. Gently massage with fingertips to ensure even distribution and absorption.

For the best results, use daily for a minimum of three months. The ingredients within the serum have different mechanisms of action and act on different parts of the hair growth cycle. Therefore, optimal results will be seen after a full hair growth cycle (120 days) to capture all benefits.

First, ensure that the cap is tightly screwed on. This will prime the pipette when it is being unscrewed and draw the necessary amount. The pipette should only fill to the correct dose and this is intentional because it is the amount you need to fill each of the four corners of your scalp.

The serum is a non-rinse formula however should you choose to wash your hair after applying then leave on for a minimum of 4 hours before to allow active ingredients to do their job.

The serum contains a negligible amount of castor oil to emulsify part of the peptide complex. This amount is exceptionally small as can be seen by how lightweight and thin and the serum is. This very small amount does not leave the scalp greasy and will not exacerbate dandruff

There are a number of anti-inflammatory and exfoliating ingredients within the formula that can be beneficial for the flaking and inflammation seen with seborrhoeic dermatitis. The formula does not contain any anti-fungals but can be used safely alongside a scalp routine for seborrhoeic dermatitis.
