Which Hair Product Actually Matches Your Goals?

Not every hair product serves the same purpose, and knowing the difference between conditioning, repair, and active regrowth can save you time and frustration.

Philip Kingsley Elasticizer is a pre-shampoo deep-conditioning mask designed to restore moisture and reduce breakage in existing strands. K18 Leave-In Molecular Repair Hair Mask uses patented peptide technology to reconnect bonds damaged by bleaching and heat styling. Our Trybello Hair Helper Spray takes a different approach entirely, delivering biotin, caffeine, and castor oil directly to the scalp to stimulate follicles and promote visible new growth.

In this guide, we break down the ingredients, pricing, timelines, and real customer reviews for all three products so you can find the right fit for your hair goals.

Trybello Hair Helper Spray

Our Trybello Hair Helper Spray targets follicles directly with biotin, caffeine, and castor oil for visible regrowth in as early as 4 weeks.

At Trybello, we created our Hair Helper Spray to do one thing exceptionally well: promote real, visible hair regrowth through safe, natural ingredients that work at the scalp level. We built our formula around three clinically studied botanicals that work synergistically.

Biotin supports keratin production and fortifies follicles, helping reduce breakage from the root. Caffeine energizes the scalp by boosting blood circulation and extending the anagen (active growth) phase of the hair cycle. Castor oil, packed with ricinoleic acid, deeply hydrates the scalp and nurtures a healthy environment for follicles to thrive.

Our formula is further enhanced with rice ferment filtrate (sake), argan oil, and ginger root extract for comprehensive scalp nourishment. To apply, simply spray 1–2 pumps onto the scalp in areas where you notice thinning or shedding.

Timeline to Results

Many of our customers observe a noticeable reduction in daily shedding within the first 4 weeks of consistent use. By week 8, new baby hairs frequently become visible along the hairline and temples. The full transformation typically develops over 12–16 weeks, with meaningful gains in volume, thickness, and overall hair vitality.

Price

Our Trybello Hair Helper Spray is $49.97 for a 50ml bottle (currently on sale for $39.97). Subscription plans and bundle options are available for those committed to their regrowth journey.

Philip Kingsley Elasticizer

Philip Kingsley's Elasticizer is a pre-shampoo deep-conditioning treatment formulated with hydrolyzed elastin to add stretch and strength to hair, castor oil and olive oil to lock in moisture and boost shine, and glycerin to help hair retain essential hydration. The product is applied to damp hair in sections, covered with a shower cap, and left on for at least 20 minutes or overnight for deeper conditioning, then shampooed out.

Philip Kingsley recommends using it once or twice per week for best results. It is important to note that Elasticizer is a conditioning and repair treatment. The formula is not designed to stimulate new hair growth or address follicle-level thinning.

Timeline to Results

Philip Kingsley states that visible improvements in hair texture, softness, and shine can be seen from the very first use, with continued improvement over time. The brand's clinical testing indicates a 46% reduction in hair breakage after a single application.

Price

The Elasticizer is available in multiple sizes: $31 for 75ml, $53 for 150ml, $104 for 500ml, and $143 for 1000ml.

K18 Leave-In Molecular Repair Hair Mask

The K18 Leave-In Molecular Repair Hair Mask is built around the brand's patented K18PEPTIDE™, a biotech-developed peptide engineered to mimic hair's own keratin structure. It reconnects broken polypeptide chains and disulfide bonds caused by bleaching, coloring, chemical services, and heat styling.

The application involves shampooing (no conditioner), thoroughly towel-drying, applying 1–3 pumps, and waiting 4 minutes without rinsing. It is essential to understand that K18 is a structural repair product. It excels at restoring the internal integrity of damaged strands, but it is not designed to stimulate new growth or address thinning.

Timeline to Results

K18 reports that most users notice improvements in hair texture, softness, and strength after 2–3 uses. For optimal results, the brand recommends using the mask for 4–6 consecutive washes, then as needed every 3–6 washes to maintain strength and resilience. Results are more dramatic on heavily damaged hair.

Price

The mask retails for $29 for 15ml, $75 for 50ml, and is available in a jumbo 100ml size.

Real Customer Reviews

Trybello Reviews

Our customers consistently share powerful transformation stories. One reviewer on Trustpilot described being skeptical at first, but after several months of using the spray, she noticed baby hairs emerging, and her shedding had reduced dramatically.

Another customer shared that she started using Trybello after chemotherapy, and the spray helped strengthen each new strand during her regrowth process, restoring her confidence along the way. A 66-year-old customer also noted that, in addition to thickening her hair, the spray completely stopped her seasonal shedding.

Trybello customers report reduced shedding and visible new growth within weeks of consistent daily use.

Philip Kingsley Elasticizer Reviews

Customers with color-treated and heat-damaged hair frequently praise the instant softness, shine, and bounce it delivers. However, some users with fine hair report that the product makes their strands overly soft, flat, and difficult to style, with no body or volume afterward. The cost is also a recurring concern, particularly for users who go through product quickly on thicker or longer hair.

Philip Kingsley Elasticizer earns praise for instant softness and conditioning, but users with fine hair find it too heavy.

K18 Reviews

K18's Leave-In Molecular Repair Mask is widely celebrated among those with color-treated and bleach-damaged hair. Many reviewers highlight a transformation in manageability, with softness and reduced frizz being the most frequently mentioned benefits.

However, the product's premium price point comes up repeatedly in user feedback, with some questioning long-term affordability. Several reviewers also mentioned that they still needed additional conditioning products, as the mask alone did not provide sufficient moisture for very dry hair.

K18 users acknowledge visible improvements in hair texture but frequently note the premium price as a drawback.

Why Trybello Hair Helper Spray Stands Out

After examining all three products, the distinction becomes clear. Philip Kingsley Elasticizer is a conditioning treatment that adds moisture, elasticity, and shine to existing strands. K18 is great for repairing damage from bleaching and heat, but it also does not address thinning or shedding at the follicle level.

Our Trybello Hair Helper Spray was purpose-built to fill this gap. Our 100% botanical formula delivers biotin, caffeine, and castor oil directly to the scalp where they can actively stimulate the follicle environment, promote new growth, and reduce shedding. Our spray is lightweight, absorbs without leaving residue, and works for every texture, whether natural, relaxed, curly, coily, or straight.

We are committed to transparency, ingredient quality, and customer care. And with our 120-Day Complete Growth Guarantee, you can try our Trybello Hair Helper Spray completely risk-free. If you do not see the results you are hoping for, you get your money back. With over 100,000 satisfied customers and a 4.8/5 rating from more than 40,000 reviews, we are confident our spray can support your hair regrowth journey.
