The complete system to grow longer, thicker, fuller hair

The Signature Set

Hair growth starts with a routine that supports every step of the process: from the scalp, to your lengths, to your ends. Because fuller, longer-looking hair isn’t just about growth alone, it’s also about hydration, protection, and consistency.

The Signature Set covers all three essentials: daily scalp support for thicker hair growth, a pre-wash treatment to help stop breakage in the shower, and lightweight nourishment to keep ends soft, glossy, and protected between washes.

Includes: Hair Growth Nourishing Spray + Deep Hydration Treatment + Hair Lengthening Oil

The Signature Set covers all three essentials: daily scalp support for thicker hair growth, a pre-wash treatment to strengthen ends, reduce breakage, and help you achieve growth you can actually see, and lightweight nourishment to keep ends soft, glossy, and protected between washes.

WOW this stuff. I am on my 3rd cycle and hard to tell but nearly through with it and never have I ever subscribed to a beauty product but I just set up my subscription. I need this every month. And that says a lot bc i was super skeptical at first and for weeks. But it takes time and after being on this for now almost 3 months my hair has never felt and looked so healthy.

I am on my 4th cycle of this stuff and am loving it. I wish they had a scalp massager to sell bc that is the only thing missing and had to buy my own on Amazon. I follow their suggested routine every day and my hair feels worlds different.

Listen to me right now, buy this set. Buy 10 of them! If you have previously bleached, medium-high porosity, fine or delicate hair, READ THIS REVIEW! As a member of Modern Beauty, I’ve bought practically every high-end brand shampoo, conditioner, and leave-in, repair mask. I’ve bought countless drug store products. I’ve tried the Abbey Young Method, the No-Poo method, you name it! It felt like no matter what I tried, my hair was never happy. Products left my hair with either snapping (too much protein), mushy (too much moisture), too stripped and frizzy (not enough moisture) too heavy and coated (product-overload) or stiff and dry (too much bond-building). I’ve spent years trying to grow my hair and the short layers never seemed to budge (regardless of regular trims and staying away from hair straighteners.) Until using this Twice as Good Hair product-line. Girl!!! My hair doesn’t feel tangled or difficult to work my fingers through after showering anymore. My hair feels strong and soft! I’ve noticed far less split ends. This line doesn’t make my hair feel heavy, greasy or dull at ALL. The ingredients are minimal! No superficial coating, no build-up. I don’t leave reviews often, but this was worth it. If you can only choose 1 thing in your cart, choose this. I personally also recommend buying a boar bristle brush. Good luck!!

I’m East Asian and just sort of assumed we all had pretty straight hair, but always wondered why mine was always so much frizzier and dry-looking than most others I knew. Switched my routine and started using the signature set and it brought my curls and waves back to life

Customer photo review of The Signature Set

I started out with just the deep hydration treatment and it made my hair feel so soft and shiny after the shower which I loved but I wanted my hair to feel like that everyday so I upgraded to this signature set and it has made such a difference!!

The Signature Set

I'm new to the world of blonde highlights and went a little overboard which really damaged my hair. I was not used to feeling brittle, broken hair and this was really able to take that feeling away. It was a little inconvenient to wait 30 minutes before showering, but it really was worth it and did more than any of the spendy leave-in masks I've been buying.

The Signature Set

The prewash mask hands down saved my hair and I am so glad I bought it before I got bleached! I had very dark brown almost black hair and I decided to do an all over bleach job. Obviously, that meant I expected my hair to be pretty damaged after it was done. So i bought this set beforehand hoping it would give my hair some relief after stripping it multiple by levels. I got the color I wanted in one go but I noticed right away that while my hair wasn't breaking or falling out it was insanely dry. After the appointment I slathered the prewash all over my hair and put on a foil shower cap. I left it on for a total of 30 min and when I washed it out I was floored by how soft and moisturized my hair felt! I'm definitely gonna keep buying these products while I have blonde hair. The daily oil has been keeping my hair shiny and tangle free which I have been loving. The spray sent smells natural nothing too strong. It will take time to see results with the spray.

The Signature Set

I bought this set from twice as goodhair because my hair was very dry and lifeless due to bleaching it, and the change has been spectacular! From the first use you notice how the hair regains its elasticity and softness. What I do is let the pre-wash treatment act for about 15 or 20 minutes and then do the other two on non wash days and result is incredible. If you have battered, brittle or processed hair, it's totally worth every penny. I highly recommend it.

The Signature Set

It’s expensive but my hair is thin and weak, it needs love and good products so I decided to invest in this. Worth it! I have been trying to only wash my hair two times a week max and I just feel like with these products makes that achievable. It leaves my hair very, very soft and lightweight. Days after washing, my hair still feels incredible. My hair overall feels healthier and less dry.

The Signature Set

Amazing product line, have purchased twice so far. After a few washes, you can tell a significant difference specially after bleaching your hair for five years straight.

The Signature Set

I have had hair thinning for a few years now. It was recommended to try this set. After 4 months of consistent use, I started to notice hair growth and my hair feels so much healthier. I'm so excited to see hair in some of the places that looked like I was thinning. Highly recommended!

The Signature Set

Used the treatment 2x a week, the spray 5x a week, and the daily oil 3x a week and it has made a huge difference in my hair texture and smoothness.

The Signature Set

This stuff saved my hair! Not only was my hair thinning, but it was also always flat, lifeless, dull, and greasy within half a day of washing. No other products I tried helped. This stuff is amazing. I have noticed my hair filling in, and my hair is now shiny and bouncy. I'm not exaggerating when I say I will never use another system. I'm a customer for life! Here are some tips from me if you are dealing with the same problems I mentioned above: -If you are using a heavy moisture shampoo, it is not going to wash the treatment out so make sure to use a shampoo that is not too heavy. - The instructions tell you to massage your scalp, do this for like 4 minutes. Make sure you do this! I really started to see growth then. -With this system you won't have to wash your hair every day (I can go two days now!). When I do wash my hair I let it sit in a t-shirt for 10 min then I spray detangler in each section and brush it using a wet brush and then blow dry on cool/medium temperature.
