How it works

Detoxifying Shampoo

This sulfate-free formula relies on the cleansing properties of soap bark extract to dissolve build-up without stripping essential moisture. Saw palmetto extract, a natural DHT-blocker, helps maintain and protect hair fullness. Lilac stem cells work to stimulate the hair at the root while sealing and repairing damaged strands. Throughout the first week of use, this shampoo will help detox the hair and scalp of chemical residue and build-up caused by other hair products.

  • Cleanses and detoxifies scalp and strands
  • Blocks harmful DHT
  • Rids hair and scalp of hazardous chemical buildup
  • Supports scalp biome

Fortifying Conditioner

Infused with active botanicals, this lightweight treatment deeply conditions with the protective properties of the Plumeria flower. Tamarind, a fruit traditionally used to strengthen hair, helps soothe scalp irritation and defend against free radicals.  Lilac stem cells work to stimulate the hair at the root while sealing damaged strands.

  • Deeply conditions and strengthens hair
  • Helps repair strand damage
  • Defends against UV exposure and free radicals
  • Detangles, softens, smooths, and adds shine

Powerful ingredients

Lilac Stem Cells

Active plant cells that repair strand damage, reduce scalp irritation, and stimulate cell energy at the root for healthier, shinier hair.

Soap Bark (Quillaja)

Found only in the high altitudes of Chile, this sustainable tree bark acts as a mild, natural foaming agent to offer a nutrient-packed alternative to synthetic surfactants.

Saw Palmetto

The berries of the saw palmetto are known to be a dihydrotestosterone (DHT) blocker. They specifically affect the 5-alpha reductase enzyme, which is responsible for converting testosterone into DHT - the hormone responsible for male and female pattern hair thinning.

Plumeria Flower Extract

Rich in antioxidants, lignin and collagen-boosting glycosides, Plumeria flower extract and enzymes can help to repair damage, protect from harmful UV rays, and hydrate the hair shaft.


Tamarind has long been used in Indian Ayurvedic medicine as its flowers are rich in anthocyanins, proanthocyanidins, catechins - and can help to control sebum production on the scalp.

Our ingredient choices—the forms, what we include, and what we don't—are all made based on what you really need.

We want you to ask questions

Our scalp wellness experts have the answers you need.

Is Activating Serum safe for women and men?

While the underlying causes of hair thinning can be different for men and women, everything we make here at Collective Laboratories is designed to work for all people–regardless of gender.

I’m not currently losing hair, but I want to prevent it. Will this help?

Yes! Prevention is the most effective measure that you can take against thinning hair. The active botanicals and science-backed ingredients in Activating Serum help nourish your scalp and maintain follicle health. With regular use, Activating Serum helps maintain your hair’s normal growth cycle.

Why is this a subscription?

You wouldn’t use an anti-aging cream once and expect to see results, right? The same goes for your hair. Consistency is key when it comes to supporting the health of your scalp and strands, and it’s the little steps you take every day that really make a difference.That’s why we decided to offer Activating Serum in a subscription – so it’s easier to continue supporting your hair every day.

When will I start seeing results?

Activating Serum starts working immediately, but it can take up to three months for you to see noticeable results simply because it takes a while for your hair cycle to respond to treatment. Patience and consistency are key; new hair doesn’t happen overnight.

Where are your products made?

We source ingredients from around the world, but we make our products in our lab in California.

Can I use these products if I’m also using prescription hair loss medication?

Yes, our products work with internal prescription hair loss medications like finasteride and topical medications like minoxidil. If you are using other topical medications, please check with your doctor first before layering treatments.
