Key Ingredients
Key Ingredients
Powered by Science-Backed Botanical Ingredients:
🌿 Ginseng and ginsenosides: Clinical research suggests that these botanical compounds stimulate key cells within human hair follicles and reduce a signal that can keep follicles in the resting phase. Ginsenosides also help follicles remain in the active growth phase for longer, supporting conditions associated with healthy hair growth.
🌱 Rosemary: Valued for its antioxidant and scalp-supporting properties, rosemary helps promote microcirculation, maintain a balanced scalp environment, and support follicle activity during the active growth phase. In a clinical study, rosemary oil was associated with an increased hair count, suggesting that consistent use supports denser, fuller-looking hair over time.
🍃 Thuja leaf/Biota orientalis: A traditional botanical studied to support dermal papilla cells, which play an important role at the base of each hair follicle. Research suggests that it helps support follicle activity and the transition from the resting phase into the active growth phase, creating favorable conditions for stronger, healthier-looking and fuller-looking hair over time.
💊 Biotin (Vitamin B7): An essential B vitamin that supports the body’s natural production of keratin, the protein that forms the structure of each hair strand. Biotin helps maintain strong, healthy-looking hair and is beneficial when shedding or thinning occurs during periods of change, including weight loss and age-related thinning.
Together, this blend of botanicals works in harmony to give your scalp and hair follicles the support they need. With consistent use, the serum helps hair feel stronger and look healthier and fuller over time. FULL LIST

Frequently Asked Questions
Every hair-growth journey is different, and consistency is essential. We recommend following the SLEEQ routine for at least 180 days to give your hair and scalp time to respond.
Months 1–3: Your scalp may feel healthier and more balanced, while your hair may appear shinier with less visible shedding and breakage.
Months 3–6: You may begin to notice baby hairs, improved volume and a fuller-looking appearance.
After 6 months: With continued use, changes may become more noticeable, including stronger, denser-looking hair and improved scalp coverage.
Hair growth is sensitive to changes within the body. As we age, follicles may produce finer strands and spend less time in the active growth phase, while hormonal shifts during menopause or after pregnancy can move more hairs into the resting and shedding phases. Rapid weight loss, restrictive diets and low protein or nutrient intake can also trigger temporary excessive shedding, known as telogen effluvium.
SLEEQ’s 4-in-1 Hair Growth Serum helps support a healthier-looking scalp environment during these periods, promoting stronger, fuller-looking hair while supporting follicle activity throughout the active growth phase.
Yes, Sleeq is a clinically tested, minoxidil-free alternative for people who want visible hair-support results without side effects or without building their routine around a medicated treatment. Our formula is designed to support fuller-looking hair and healthier roots while avoiding the greasy, sticky feel and scalp discomfort that some people experience with minoxidil products.
No. Sleeq does not contain minoxidil, so it is not designed to cause the initial shedding phase often associated with minoxidil. The formula is lightweight, non-oily, and non-sticky, absorbing directly into the scalp without weighing hair down or getting in the way of styling.
Consistency is what drives results. Many users notice a fresher, more balanced scalp within the first week. Around week 4, hair can begin to look stronger and healthier from the roots. With daily use, visible improvements in hair fullness and scalp coverage are expected around week 8.
No. Sleeq is a no-rinse, leave-in serum. Let it absorb and wash your hair on your usual schedule. You do not need to shampoo every day to use it consistently.
Absolutely. Apply Sleeq directly to the scalp on dry or towel-dried hair, then let it absorb before adding heavier oils, leave-in products, or styling products. It is a no-rinse formula designed to fit easily into your existing routine without making hair feel greasy or heavy.
Use Sleeq once every 2 days for the best results. Regular use gives the formula the consistent scalp contact it needs to support healthier-looking roots, less visible breakage, and fuller-looking hair over time.
You can apply Sleeq to a dry scalp or to towel-dried hair after washing. Avoid applying it to dripping-wet hair so the serum can stay where it belongs, directly on the scalp and thinning areas.
Use the precision applicator to apply a light, even layer directly across the areas you want to target, then gently massage it into the scalp. Focus on the scalp rather than coating the hair lengths. More product is not better; consistent application is what matters.
