Ulo’s Hair Growth Supplement — Backed by science and hairstylists (2025)

Stronger, longer hair in 90 days or less? With Ulo’s best-in-class Hair Growth Supplement, you could be well on your way to a brand-new mane.

The hair growth market is flooded with expensive topicals — oils, masks, shampoos, conditioners, sprays, and serums designed for various concerns. However, hair growth supplements have also emerged as a promising alternative in the crowded category, and many experts suggest that a pill could deliver superior results.

Ulo co-founder Deep Patel is among those pioneering a new kind of hair growth product. A once-a-day pill that is designed to nourish your hair from within, helping tackle hair loss at its roots.

“Ulo’s Hair Growth Supplement takes a comprehensive approach to hair health by addressing hormonal, inflammatory, and nutritional factors,” Patel explained.

His team has selected a range of clinically-tested ingredients that help stimulate hair follicle cells and support scalp health while also incorporating antioxidants and vitamins that the body is able to use for energy.

“It features therapeutic doses of well-researched natural ingredients like saw palmetto and L-carnitine L-tartrate,” said Patel. “It also includes vitamin D3 to support healthy hair cycling and astaxanthin along with red clover extract for an antioxidant boost to the hair follicles.”

The Ulo Hair Growth Supplement is backed by science. Saw Palmetto was tested in a 16-week study and shown to reduce hair shedding by 29% and increase hair density by 5%, with no serious side effects reported.

Another ingredient in Ulo, L-carnitine L-tartrate, was researched alongside other hair-promoting ingredients and led to a significant increase in total hair count and density. The growth was attributed to enhanced nutrient transport into hair follicles and prolonged anagen phases.

Some of the other ingredients go well beyond the scalp. The Ulo supplement also combines biotin and zinc — both of which play a role in promoting hair health by addressing deficiencies linked to hair thinning. Plus, it’s filled with fatty acids and proteins to help fill other nutritional gaps.

Ulo is also very selective about what is not featured in the formula. “Unlike many supplements, it is free from fillers and uses ingredients at doses backed by clinical studies, providing your hair with the foundation it needs to look and feel fuller and thicker,” Patel added.

According to Ulo, many users have seen reduced hair shedding within eight to 12 weeks and achieved stronger, healthier hair between three to six months.

The supplement is formulated to be well-tolerated. However, it’s always important to check with your healthcare provider before starting a new supplement — especially for those with underlying health conditions, those who are pregnant or breastfeeding, and anyone with allergies.

Ulo Hair Growth Supplement FAQs

To further evaluate the effectiveness of the Ulo Hair Growth supplement, The Post consulted two trained cosmetologists — Gabrielle Garrison and master stylist Arnela Rizai.

How do the ingredients in Ulo’s Hair Growth supplement promote hair growth?

“Some of the main ingredients in the Ulo hair growth supplement are biotin, hydrolyzed fish collagen, and organic pumpkin seed oil,” shared Garrison, who has a degree in cosmetology from Penrose Academy and has been working behind the chair for five years. “All of these ingredients help with the production of keratin in your body, which can promote healthy and strong hair.”

Are there any potential side effects?

“You can overuse certain ingredients in this product, which can lead to the product not working properly, so it is important to use it as directed,” Garrison explained. “Over time, if you take too much biotin and collagen, it can create too much protein, which could eventually lead to stomach or kidney issues.”

Are these supplements suitable for all hair types?

“Hair growth is different for everyone,” suggested Garrison, who likes to provide a tailored hair growth plan to her patients looking to achieve longer locks. “However, all hair types can benefit from hair growth supplements. Making sure you are also nourishing your hair and body in your hair growth journey is key.”

How long might it take to see hair growth?

Patience is important, according to Rizai, who has 15 years of experience in the industry and opened a hair salon in Massachusetts last year. “Most studies and anecdotal reports suggest that with consistent use, you can start noticing improvement in about three to six months,” she suggested. “Hair grows approximately half an inch a month, so stick with it and give your follicles time to shine.”

Will these supplements work?

“Absolutely!” Rizai exclaimed. “When used consistently and as part of a balanced lifestyle, this supplement can help support healthier, stronger hair — especially if your hair loss is linked to nutritional deficiencies or hormonal imbalance.”

She has added that results can vary from person to person, and a holistic approach that includes a good diet and proper hair care routine can make a difference in the amount of growth you’ll experience.

Are supplements generally more effective for hair growth than topical products?

“Both have their perks,” shared Rizai. “The best approach is often a combination of the two! Supplements work from the inside out to address nutritional gaps and hormonal issues, while topicals like serums and shampoos target the scalp directly. For instance, products like minoxidil have solid clinical backing for topical use. Think of supplements as nourishing your hair at the roots, and topicals as the cheery on top for that extra boost.”

Besides supplements, what else can you do to try and grow your hair?

Beyond incorporating a supplement like Ulo, Rizai has offered some extra tips for those looking to achieve stronger, healthier hair.

“Eating a nutrient-rich diet with plenty of proteins, vitamins, and minerals is key. Regular scalp massage can boost blood flow and give your follicles a little extra love. Try to avoid excessive heat styling and harsh chemical treatments that can weaken your hair,” she encouraged.

Rizai has also highly recommended taking a blood test to check for vitamin and hormone deficiencies. But more than anything, she emphasizes that consistency is key. Nurturing your hair takes time.
