Review summary

Based on reviews, created with AI

Reviewers overwhelmingly had a great experience with this company. Customers frequently praise the products, noting significant improvements in hair health, thickness, and growth. Many people have experienced reduced hair loss, stronger hair, and even new growth, which has boosted their confidence. The products are often described as effective, easy to use, and having a pleasant smell and taste, with some reviewers highlighting the positive impact on their nails and eyebrows as well. However, some customers were not happy with the product, mentioning issues such as hair feeling tangled, heavy, or flat after use, and some did not see the desired hair growth results even after consistent use. A few people also expressed frustration with faulty product pumps and questioned the verification of celebrity endorsements.

Brilliant products and customer service

Not only do Hair Gain have brilliant products but their customer service is very good too.
I originally started using their hair gummies and then went on to their hair mask both of which have really helped the growth and condition of my hair. My hairdresser commented at my recent visit that my hair lengths were no longer wispy and only needed a slight trim after several months of growing. I am now using their shampoo and conditioner which leaves my hair feeling great. I recently had to deal with customer services and they were really helpful. It’s lovely to know that they seem to care about their customers and provide genuine great products. Thank you Hair Gain x

We’re thrilled to hear you’ve seen such a difference with the gummies, mask, and now the shampoo and conditioner (especially that comment from your hairdresser!) It’s also great to know our customer service team were able to help. Your kind words really mean a lot to us. Thank you for choosing Hair Gain x

A good shampoo and conditioner

A good shampoo and conditioner, they need to be used together as your hair feels knotty after shampooing but a tiny amount of conditioner sorts it out and my hair feels lovely and soft. Too early to say if the thickness of my hair has improved but I will certainly continue using.

I was surprised by the excessive…

I was surprised by the excessive customs costs once the parcel arrived at my door - having no indication in advance of the likely fee. Your T&Cs do state that the customer is liable but you don’t give any transparency on likely costs. Unfortunately the additional €28 customs for a delivery in France make your products too expensive. I regularly order products from the UK and those companies seem to do a better job of import costs.

Hello Sofia,

We're sorry to hear this has been your experience. There are a lot of reasons that can cause hair loss, whether it's stress or seasonal. 
Please see a link to our blog that gives more details regarding this. Seasonal Hair Shedding Explained - Hair Gain Now

For prolonged hair loss, and if you are worried, we recommend speaking with a healthcare professional or trichologist as they may be able to give you more information about your scalp and what can work best for you. 

Feel free to reach out to enquiries@hairgainnow.com if you'd like us to recommend our Trichologist. 

Kind regards,

100% works wonders!

100% works wonders!
I had twins in my early 40’s and so had a double whammy of post pregnancy / breastfeeding hair teamed with perimenopausal hair = thinning x 1,000 …I’ve been using Hair Gain Now for 2-3 months (plus I do take A&B collagen) and it’s definitely helped make my hair super thick and super soft, it’s insane, literally doubled in volume and thickness. I’m so pleased! 🙌🏼

Taste nice but no hair gain yet

Bought 2 months of hair gummies, tasted nice and good quality.
I thought give another month but no difference to hair growth so far.
So jury out currently if they work.
Hope so as quite expensive.

This product has been a total game changer. My curly hair feels soft, silky, and shiny, and it straightens beautifully without feeling heavy. After blow‑drying, my hair looks so smooth and healthy. I’m genuinely impressed.

Great product

Have been taking the capsules for a number of months plus using the hair mask 1 or 2 times a month. Recently I bought the shampoo and conditioner. Last week I had my haircut, my haidresser hasn't seen my hair for about 2 months;she could not believe the great condition of my hair. She said it was soft, no split ends (some dryness from styling) and a lovely shine. She is not the first to notice!
