This serum is great in that applying it at night does not make hair oily or greasy by morning.Havent been using it long enough to see any massive results but due to the ease of application i will continue using.

Amazing!

I love that I can use this in my hair every day without it feeling greasy, something I’ve always struggled to find, especially with my finer hair. I’ve been using it for around four weeks now, and I’m already starting to notice new baby hairs, particularly around my hairline. I’m really excited to see how my hair continues to improve with ongoing use.

Effective Hair-Growth

I have used this on 3 areas of my hair for about 2 weeks, now, and have found a definite sign of new hair growth. I am hoping for this to continue.

Use nightly, no oily residue.

Yes, I recommend this

Easy to use, light and pleasant fragrance with no oily residue. It seems to be nourishing, but results not evident yet although expecting positive results soon.

I have been using this product on and off as I keep forgetting to use it, it does feel nice it isn’t greasy or smelly which is good as I have thin hair and wouldn’t like anything to make me need to wash it due to product being seen, I haven’t noticed any difference as yet but I haven’t been using it consistently but will continue on

Got this product by recommendation and I’mhappy I did. I’m getting regrowth in the areas my hair was thinning. It’s a slow process but it’s definitely happening. Great product.

Good serum

Yes, I recommend this

I can't yet comment as I haven't used it long enough, however, it is pleasant on the scalp, not sticky or greasy. After applying at bedtime, hair seems absolutely fine the next day. No itching and my scalp is quite sensitive.

No, I don't recommend this

Very watery so you need to catch it and massage before it runs on to your face. Been using for nearly a month and no difference as yet.

Used this product religiously after a period of hair loss. Has made a huge difference, smells luxurious and only a little is needed so it lasts such a long time.I repurchased as soon as I was close to running out!

I’ve been using this for over six months along my hairline to encourage my baby hairs that have thinned through perimenopause to grow. I have seen amazing results. I can even tie my hair in a ponytail without a weird wiggly hairline.

Seeing progress

I started using this serum having tried a few others. The formulation is great as it doesn’t make my hair greasy and I think it is having an impact already. Keen to see what happens with longer term use.

Night serum

Originally posted on TYPEBEA

Yes, I recommend this

I am getting real results from this nightly serum. New hair has appeared at the receded hair line. One extra (huge) benefit is that the serum adds body to the root of hair. I would usually need large rollers to get that lift. Delighted with it. Highly recommended

I have recently switched to using the Typebea shampoo, repair mask and the overnight serum and it’s changed my hair completely! My hair no longer gets oily like it used to and feels super clean with every wash. It has volume and so much shine. The serum has been a game changer! I use it on my hair as well as my eyebrows haha. I’m actually in shock at how much hair is growing on my head. But also my eyebrows have gone thicker ! And I’ve only just finished my first bottle! I do use one of those derma rollers for your scalp on my scalp and eyebrows once I’ve appplied the serum and I feel like this has helped speed up the process perhaps. I Love Love Love this brand so much. Need a lifetime subscription ☺️
