Haircare brand founder says six ingredients can prevent loss & promote growth – but beware an ‘extreme’ mistake
HAIRCARE products such as shampoo and conditioner can prevent shedding if they contain six key ingredients, says an expert.
She shared must-try tips for keeping locks healthy and promoting growth.
Sarah Carrino is the founder of the UK-based lifestyle brand Just Flex, which sells health supplements and activewear.
Among her latest products is the Just Flex Hair Skin & Nails Complex, gummies containing biotin, vitamins C and E for healthier hair and glowing skin.
Speaking to The U.S. Sun, she shared advice for luscious locks.
INCREDIBLE INGREDIENTS
Carrino said there are several ingredients to look out for when buying haircare products to prevent or reduce loss.
Among them is niacinamide, which is a form of vitamin B3.
“Niacinamide is an excellent ingredient for hair loss shampoos and conditioners,” she said.
“It improves circulation to the hair follicles, delivering more nutrients and oxygen to promote stronger, thicker hair growth.
“It also reinforces the skin's moisture barrier on the scalp.”
She said caffeine is often added to hair loss treatments because it’s believed to promote growth.
She said it stimulates the hair follicles and extends the growth phase of the hair cycle.
Another nutrient known for its lengthening properties is biotin.
“Biotin is a B vitamin that plays a role in the production of keratin, the key protein that makes up hair,” Carrino said.
“Including biotin in hair supplements or products can support healthy hair growth."
Ingredients that improve scalp health are also among her recommendations.
“Salicylic acid is a beta hydroxy acid that gently exfoliates the scalp, removing dead skin cells and buildup that can clog hair follicles and inhibit growth,” she said.
“It is often included in medicated anti-hair loss shampoos.”
Just be natural with your hair. No extreme heat from appliances like hairdryers and straighteners.

She revealed Capilia Longa is “faster acting” than over-the-counter treatment minoxidil.
“Capilia Longa is a plant-based ingredient clinically proven to reduce hair loss by up to 89% and increase hair density by 52% over 150 days of use,” she said.
“The herb saw palmetto contains fatty acids and plant sterols that may help block 5-alpha reductase, the enzyme that converts testosterone to DHT, a hormone linked to hair loss.”
What causes hair loss?
Carrino revealed the seven common causes of hair loss in women:
“1. Female pattern baldness (androgenetic alopecia): This is the most common cause of hair loss worldwide," she said.
“It is hereditary and caused by hormones called androgens and genetics. Hair gradually thins all over the scalp, and the hairline recede.
“2. Telogen effluvium: This is temporary hair shedding caused by stress, illness, nutritional deficiencies, hormonal changes (like after pregnancy), or certain medications.
“Hair falls out more than usual, but regrowth is possible once the trigger is resolved.
“ 3. Alopecia areata: An autoimmune condition where the body attacks hair follicles, causing patchy hair loss on the scalp, face, or other areas.
“It can lead to total baldness in some cases.
“4. Traction alopecia: Caused by tight hairstyles like braids, ponytails, or extensions that pull on the hair over time, leading to permanent hair loss
“5. Nutritional deficiencies: Lack of nutrients like iron, protein, zinc, or vitamins can contribute to excessive shedding.
“6. Medical conditions: Thyroid disorders, diabetes, lupus, anemia, and scalp infections like ringworm can cause hair loss.
“7. Medications: Certain drugs used for cancer, arthritis, depression, heart problems, and birth control can lead to temporary or permanent hair thinning.
“Other less common causes include physical or emotional stress, hormonal imbalances, and aging.”
SPLENDID STYLES
Carrino said hair loss can be “extremely upsetting” but she’s experienced clients regain their confidence by following her hair growth tips.
She recommended avoiding "extreme heat" styling tools such as hairdryers and straighteners in favor of being natural.
She said the time it takes for hair to regrow varies but careful styling and nutrient-rich products can help.

“One of the best options, especially for those with curly or coily hair textures, is to simply wear the hair down and natural whenever possible,” she said.
“This gives the hair and scalp a break from any tension.”
